About 10 years ago when this high fps stuff started to become better and better in dslrs, all the sports shooters had a freak out because they got worried that their license fees would go up because events would charge them for the motion picture license not the still license. I don’t know if this ended up becoming true but it was all the talk at WEVA for years. Sony have always made great cameras, unfortunately their primes don't hold a candle to Canon or Nikon. Anyone who reaaalllly cares about this feature is probably shooting fixed (tho I've been out of the industry a long time I'm sure it's changed)


A common practice among Sony shooters is to adapt Canon/Nikon glass to the Sony body if Sony glass doesn't cover a shot. Auto Focus takes a small to complete hit when this happens but it is less of an issue for stills than video.


I thought Carl Zeiss made their lenses? Not checked, but I have sworn by Zeiss for twenty years in their various mounts and incarnations.


Not all of them. Sony designs/manufactures some (known as the Sony FE and E lines) and Zeiss designs/manufactures some (Zeiss Batis, Loxia, and Touit lines).

To make this even more confusing, some are designed by Zeiss but manufactured by Sony and carry both of their logos (nicknamed Zony; e.g., Sony Zeiss Sonnar T* FE 55mm f1.8)


Not all Sony lenses are Zeiss, only the most expensive ones. Most of the low end lenses are just Sony branded.


iirc, Sony does it's own manufacturing but works with Zeiss on most of it's lenses. In my personal opinion, and really I think it's pretty wanky to debate this stuff too much, but personally I like the fluorite UD glass from Canon, imo, has the best colour clarity and definition.


Canon glass is fine if you're a professional, Zeiss and Leica is superlative but it still depends on focal lengths. I still have my Contax mount 50/1.4, because nothing save for some Leica lenses exhibit the same qualities on 35mm format. If I were a sports photographer I'd probably go with Canon though.


Despite being very good to my stuff, my Canon cameras and lenses just break. I'm going Sony next time.


Impressive camera for sure but something missing in a couple articles I've seen on this is glossing over the fact that Nikon/Canon have a huge library of lenses.

With photography it's largely the lens that drives the photo(which makes sense when you think of photographing in terms of painting with light). Until you see Sony breaking out the 300mm F2.8, 400mm F2.8, 600mm F4 and others you won't see much pick-up on the segment they're targeting(1DX, etc). For instance a 400mm F2.8 goes for 2x the cost of this camera alone(~$10k).

There's adapters for EF->Sony, however they're hit and miss on functionality and focusing speed.


OTOH, being a mirrorless system you can use an adapter for pretty much any lens ever made, not only Canon but any possible glass that has been used in the modern history of photography. And some times without any significant loss of functionality.

But yeah, its true. Professionals take to stick to brands for a lot of reasons. Investment already made in lenses, repairability, how easy is to find a colleague during a job that can loan you some missing equipment, etc...

Sony is not going to conquer the professional market overnight, granted, but it's important to have this camera in their catalog to start moving things in that direction.


Yeah there's adapters but they're pretty spotty and pricey. I actually looked pretty deep into converting to Sony from Canon a while back but keeping my lenses(I can't give up Canon's 35mm F1.4 and 135mm F2.0, they're not an equivalent in Sony's system). However auto-focus didn't work or was really slow on quite a few lenses so I ended up going with a 6D instead.


Sony has a 300mm f2.8 and 500mm f4, so it's not a million miles behind.

The system as a whole is getting pretty compelling TBH.

Using a camera that can focus track and calculate exposure at over 20fps with nearly 700 auto focus points across almost the whole frame would for sure let me capture stuff I couldn't on any other camera.

And that's not to mention the silent shutter at this speed - I could literally capture photos I wouldn't be allowed to (golf anyone???) with a mechanical and noisy shutter.

Even if I did it on a 500mm f4 and cropped in some of those 24mp!

I'm a Nikon guy (well, I did shoot with the old a900 and some Canon/Olympus stuff too) and I'd certainly consider working very hard to deal with any lens short comings with a camera this capable.


Sony's been doing an impressive job. But another factor that dovetails with Canon/Nikon system investments is that all of these big DSLRs have features that are already well past the point of diminishing returns for a lot of people. I have a Canon 5Diii and I have no urge to upgrade it much less switch systems. (To be honest, I don't even use it all that much because I have other cameras that are far smaller and do a perfectly adequate job for most things.)


Not being a camera guy, can someone explain to me why all these stats are awesome? I mean, they sound awesome, but I'm a sucker for people telling me things are awesome.


This is Sony's first true professional mirrorless camera.

The professional camera industry is going through a paradigm shift. From SLRs (cameras with a mirrors that flap with each photo and make the unique clack sound) to Mirrorless. You needed the mirror during the film days, because you needed to see what the lens was seeing. Now, you can capture what the lens is seeing from the sensor into an electronic viewfinder.

However, there is still an opinion that an SLR (Nikon or Canon) is a real professional tool. From built quality, to focus speed (phase detect), frames/second, battery life, dual card capture, etc.

Sony's new A9 is designed to go head to head against the top of the line professional cameras from Nikon and Canon. At least on many of the specs.

That said, I'm still not convinced it's going to be as robust as a Nikon D5 or Canon's 1Dx, etc.

I'm a Nikon user now (was canon for a long time) and I abuse my camera a lot. From rain, extreme cold, etc. And the camera continues to work. Many of my photographer friends on FB are unhappy with reliability of the Sony's A7 series and switched back to Canon and Nikon due to reliability issues. So even though the A9 has all the specs, it may still not be the camera pros shooting Olympics, etc. switch to.


It lacks super telephoto lenses, advanced lenses (such as tilt shift), and more flash options to make it a "true" professional camera.

I also agree on reliability. I broke an A7 II after 5 months of mild usage. I don't think the sensor stabilization system is ready for pro usage


They're improving on one front, they also launched a 100-400mm super telephoto lens today:

http://www.sonyalpharumors.com/sony-announces-the-new-100-40...

But yeah, they have a long way to go to match the lens offerings of Canon / Nikon.


The industry has been hammering nails into the DSLR's coffin for a while now, but to me this looks like the last fastener of all.


What this article totally misses is that this is Sony's flagship offering not for all professional photographers, but specifically for professional SPORTS photographers.

Sports photographers need super fast continuous shooting so you can get 20 shots of that epic catch in one shutter press and choose the best one. Likewise 1/32,000th of a sec shutter speed is twice as fast as most cameras' 1/8,000th of a sec fastest shutter speed, which helps to freeze quick motion.

The high number of AF points is a sports feature too - one area that mirrorless still significantly lags traditional DSLRs is that their AF systems are not as fast as the type used in DSLRs, which have dedicated AF sensors (mirrorless does AF off the imaging sensor), so a ton of AF points is one way mirrorless tries to narrow the AF gap.


> their AF systems are not as fast as the type used in DSLRs

Heh, my Canon 600D's autofocus is EXTREMELY slow D:


Yes, but 600D is not meant to be a sports camera :)


1/32,000th is 4x faster than 1/8,000th, no?


Might it also be useful for wildlife?


Yep, wildlife too. Sports and wildlife have been the weak points of Sony kits due to AF speed and lack of long native lenses (they announced 100-400mm lens today too).


I was immediately thinking of the hummingbird example and then looked up the stats and it has a wing beat 70 times per second; So this is more than fast enough as I would imagine are many other cheaper offerings for that refresh rate.


It's a large format sensor (35mm) which captures a lot of light which means that it works better in low light, without flash. Being mirrorless makes the lenses cheaper because of optics reasons (pro lenses tend to be very expensive).


>Being mirrorless makes the lenses cheaper because of optics reasons

Hmm, it should theoretically make wide angle lenses a bit cheaper because they won't have to use retrofocus designs. But I think the actual price of the lens is going to be determined by what pro photographers are used to paying for fancy wide angle lenses.


They'll be smaller and probably better, but not cheaper :)


35mm is full frame, not large format. Large format starts at 4"x5". Very few large format sensors have ever been built.


This is mainly for useful for sports professional photography. It enables you to get some great shots the easy(er) way and sell them to sports news outlets.


Now people with more money than sense will be able to take bad photos faster than ever before.

After autonomous cars will come autonomous cameras--the camera will be a better photographer than you are, so it won't need you to actually operate it. It'll just fly around on a drone. Have its own gallery shows. Win Pulitzers.


DSLRs with mirror mechanisms are now officially a technological dead-end.

This new camera does things that are not possible with DSLR bodies, including SILENT 20FPS shooting, WITHOUT BLACKOUT, WITHOUT DISTORTION FROM ROLLING SHUTTER, and with SHUTTER SPEED UP TO 1/32000 -- very impressive. Sports and other pro photographers that need high-end performance will take notice.

Mirrorless cameras are now clearly the future of pro photography. Canon and Nikon should be very worried.

EDIT: Here's a good first look explaining the importance of all new features: http://briansmith.com/sony-a9-camera-fe-100-400mm-gm-lens-re...


>This new camera does things that are not possible with DSLR bodies, including SILENT 20FPS shooting, WITHOUT BLACKOUT, WITHOUT DISTORTION FROM ROLLING SHUTTER, and with SHUTTER SPEED UP TO 1/32000 -- very impressive

It's impressive, but it's irrelevant to 99% of photography.

I'd personally rather have an optical viewfinder than all of those features, impressive as they are.


Unless you, personally, account for the other 99% of the photography market I wouldn't hand wave this camera that fast.

It's a very specialized piece of equipment for a very specific user, sure, but Sony has other bodies suited for different jobs. What the A9 shows is that there are advantages unattainable to mirror systems. As technology matures and cost of entry lowers, the more limited and cumbersome mirror systems will be cast away.

Optical viewfinder, albeit nice, won't sustain the whole market for DSLR. The advantage of no having vibration or rolling shutter or silent operation, will eventually drive people to mirrorless systems.


I was commenting on the suggestion that DSLRs are now obsolete. For sure this is a highly capable camera and there are some advantages to going mirrorless.

>The advantage of no having vibration or rolling shutter or silent operation, will eventually drive people to mirrorless systems.

Vibration is a red herring. Mirror damping for small format DSLRs has been a solved problem for decades. In any case, all of these advantages can be obtained with a DSLR too when it's in mirror lock-up mode.


> The advantage of no having vibration or rolling shutter or silent operation, will eventually drive people to mirrorless systems.

Those are mostly advantages of shutterless systems (which DSLRs can be and some have been, though sensor quality issues made them niche and actually mitigated some of the advantages; shutterless cameras historically have still had rolling shutter effects, especially at "shutter speeds" higher than those current DSLR mechanical shutters operate at, which is why those shutter speeds are used), except the vibration one is affected by both mirror and shutter (though DSLRs already have mirror lock-in to address the mirror impact.) Also, mirrorless has battery impacts compared to DSLR.

So what this says to me is that, if the sensor is really qualitatively good enough to allow this without the problems shutterless cameras have faced before, Sony has a sensor technology lead that will give them a better market position. But assuming everyone else catches up on sensors, DSLRs aren't what is in trouble, its mechanical shutters that are doomed.


> I'd personally rather have an optical viewfinder than all of those features, impressive as they are.

Why? OVF doesn't show you what your picture is going to look like. You have to move from the viewfinder to look at the LCD to check exposure then go back to the viewfinder, repeatedly.

EVF shows you exactly what your picture going to look like.


>Why?

Uses less battery and works much better in low light.

>You have to move from the viewfinder to look at the LCD to check exposure then go back to the viewfinder, repeatedly.

If I want to check the histogram then I shoot with the mirror locked up, but modern DSLRs have very reliable autoexposure systems, in my experience at least.

>EVF shows you exactly what your picture going to look like.

It shows you what it will look like on a small screen with low dynamic range. You have to look at the histogram to see if you're losing shadow/highlight information.


>You have to look at the histogram to see if you're losing shadow/highlight information.

Sure...which you only get on an LCD. IMO the only dealbreakers with EVFs are refresh rate, battery consumption and color gamut. If I were a camera maker, I would not be banking on any of those not being solved problems in the next five years.


I think it's pretty optimistic to think that the battery life issues will be solved in the next five years. It doesn't look like we're going to be getting significantly more energy dense batteries or lower energy display technologies in that timeframe. (Not in consumer products, anyway.)


On the launch live stream, one of the commentators said that he used the a9 all day, took 2,200 pictures with autofocus, and still had 40% battery life remaining -- This is approaching 'solved' for the majority of camera users. I've got an older mirrorless with a subpar battery so I'm definitely sympathetic to the issues but anything over a few thousand pictures is good enough.


I don't think battery use is a real important issue simply because the cost of batteries is so low. I was able to buy two extras for my a6000 for about $19.


> It shows you what it will look like on a small screen with low dynamic range. You have to look at the histogram to see if you're losing shadow/highlight information.

EVF shows me the histogram (can toggle it on and off without moving my eye).


That's cool. However, there's no fundamental reason why a DSLR viewfinder couldn't show a histogram too. It's not an important feature for me personally, but YMMV.


> However, there's no fundamental reason why a DSLR viewfinder couldn't show a histogram too.

You'd need to have to reduce the optical image size to make room for an LCD display, have a HUD to overlay a digital image over the OVF optical image, or have another moving mirror and toggle between EVF and OVF to do that on a DSLR.

Which is to stay that an in-viewfinder histogram is possible but not easy for a DSLR.


Yeah, I was assuming it would be accomplished via a HUD. The technology is already used in other consumer products:

https://en.wikipedia.org/wiki/See-through_display

"Small scale see-though LCDs have been commercially available for some time."


And available in which cameras? Not even sure what you are arguing here...


Just that this feature could be added to DSLRs, so it's not inherently an advantage of mirrorless cameras. Of course if you already have an EVF there is no additional cost associated with providing the histogram overlay. But if everyone starts demanding in-viewfinder histograms, DSLR manufacturers could add that feature.


> OVF doesn't show you what your picture is going to look like.

It's more accurate in many respects, and lower latency, than current EVFs.

> EVF shows you exactly what your picture going to look like.

An idealized EVF with perfect quality and a resolution equal to that of the sensor would do that, sure.

But real EVFs don't.


Name one aspect in which OVFs are more accurate. Many of them are not even exactly 100% of the sensor image, and they do not give any preview of what the actual image is going to be. EVFs give a pretty good perception of the image. They especially give you a good preview of the exposure. With the latest generation of EVFs, as this Sony camera has, their lag is actually lower than the one of an optical viewfinder. The OVF by itself has of course no lag, but when you press the shutter, the mirror has to swing away before you can take a picture. A mirrorless camera can instantly capture a picture, effectively having the smaller time differential between the VF and the picture taken.


While physical look and feel and a "nice" interaction experience in general may be important for 80% of camera buyers: The cameras that shoot 80% of the photos you see every day are built to different criteria.


This camera, priced at $4500 _and_ too large to fit in a trouser pocket, is irrelevant for >>99% of photography, but I think that's irrelevant. I doubt Sony plans to sell millions of them each month.


OP was claiming that mirrored cameras were now obsolete.


I read OPs comment as "100% certain on the way out", not as "now obsolete".

That mechanical mirror is fairly expensive to build and imposes some restrictions on lens design (the back of the lens can't move too close to the sensor), and both will go up over time (the mirror hardware will get more expensive because fewer and fewer mirrored cameras are sold, and larger sensors require larger mirrors)

As far as I can tell (corrections welcome), the main advantages of a mirror are battery life and behavior in low light conditions (it isn't easy to rapidly update a LCD viewfinder in low light conditions, and that viewfinder may be too bright). Battery life becomes less of an issue with better battery technology. That leaves low light photography. I don't think that, over time, will be sufficient to keep a market for such cameras.


>That mechanical mirror is fairly expensive to build

Hmm, is it though? I don't have any data on that, but I wouldn't necessarily assume that a relatively simple mechanism of that sort is expensive to manufacture when cheap labour is available. I suspect that the cost of the mirror mechanism is a tiny fraction of the overall cost of making a high end DSLR.

>imposes some restrictions on lens design

For sure, but the de facto biggest lens systems are for DSLRs. Given the usability of old lenses (on Nikons at least), that's not going to change for a very long time. The restrictions on lens design have not proven to be a problem in practice.

Also, there are reasons to use retrofocus designs other than the presence of the mirror. Ultrawides with non-retrofocus designs have serious vignetting issues. I have a 75mm Schneider Super-Angulon that I use with an old 4x5, for example, and the corners can be around 1.5 stop darker than the center. The problem is bad enough that they make dedicated filters to compensate: https://www.schneideroptics.com/ecommerce/CatalogSubCategory...

Also an interesting quote from https://www.bhphotovideo.com/explora/photography/hands-revie...

>If there’s a downside to non-retrofocus lenses, it would have to be vignetting, which depending on the lens, can be 1 to 2 stops of light falloff toward the corners of the frame. When coupled to digital cameras, these issues can become exaggerated because, ideally, light shouldn’t strike the sensor at angles greater than 90° [sic], which is the case when it comes to non-retrofocus lenses.

So you might find that mirrorless cameras end up with similar wide angle lens designs to DSLRs.


Their DSLRs can all function in mirror lock up mode. It's straightforward to delete the viewfinder and have a comparable product.


Sony uses a mirrorless specific format with the lens mount closer to the focal plane than would be possible with a DSLR. This has some nice benefits for the optical design; you're removing a constraint that happens to be particularly painful for image quality.

For many decades this was the big advantage of rangefinders such as the Leica M.

For Canon or Nikon to do the same it would mean re-releasing their entire line (or duplicating it). Canon kind of doing this with their EOS-M series but they only have a few low-end lenses available. Lenses product cycles are measured in decades, so this is a massive undertaking.

Sony was never successful in the DSLR business and they have a much smaller library of lenses so it makes sense that they are abandoning it completely.


Or keep the viewfinder and have a strictly superior product.


Also more complex and with more things that can go wrong due to mechanical failure


Sure, it's more expensive in both initial and operational cost and provides a strict superset of the functionality. This is a fairly common description of what distinguishes higher-end professional products from lower-level and consumer products.

Until digital viewfinders on camera are indistinguishable in quality (both accuracy and latency), there will be a qualitative advantage to having a through-the-lens optical viewfinders available (even if there are circumstances where it remains advantageous to disable it), which means SLR with lockup mode is going to beat mirrorless when that matters.

Eventually, sure, the viewfinder gap will narrow.


And heavier, larger and more expensive to manufacture.


The latest generation EVFs are superior in most aspects. For example the new Sony does not have a viewfinder blackout like DSLRs have.


I don't know, - I mean the mirror is bulky and a moving part that can break, but the OVF will be better than EVF in many scenarios.

Cameras with a mirror can shoot with an electronic shutter when needed, but will usually need to do so in "live view" on the rear display - i.e. there is no EVF. Cameras without mirror on the other hand can't use an optical viewfinder, but has an EVF.

Obviously the shutter and fps features of this particular camera are impressive and beats most DSLrs, but there is nothing inherent about DSLr's vs mirrorless that prevents all cameras of both kinds to pull this off soon.

I think the size of mirrorless cameras is a cool feature when you slap on a 35/2.8 on it or similar, so you benefit from the reduced size. Throw on a normal 24-70 zoom lens or similar, and the size difference between a DSLr and a mirrorless is gone.


> WITHOUT DISTORTION FROM ROLLING SHUTTER

Where do you read this? I see no mention of a global shutter.

Rolling shutter is a misleading name. It is an attribute of the sensor, not of any mechanical shutter in front of it. It maybe should have been called rolling read-out. The CMOS image sensor is read out, and reset, line by line --- instead of an image being taken by the whole sensor at once (as in a global-shutter sensor). Therefore the image taken by line 2 is a moment later than the image taken by line 1, and so forth.

Global shutter sensors are rare. They don't really cost a lot more, but historically they lose two or more f-stops of exposure latitude and light sensitivity. This is because each photodiode in the sensor is crammed with a bit more circuitry, to store the charge until it is read out, so that a consistent image can be frozen all at once.


Now all Sony has to do is design a real ruggerized body to go with it.

A Canon 5D mk3 or mk4 can withstand a 6 feet fall (I've been through this several times). A Canon 1DX can be thrown in sand, dust and kicked like a soccer ball and still work. A Sony mirrorless camera won't work after mild rain or slight fall.


I wish cell phone cameras would pick up on-sensor phase detection autofocus. It's the one thing that really holds them back. Contrast detection is just too slow!


That has been available for several years. iPhones 6 and above (for example) include "focus pixels", which is Apple-speak for PDAF.

http://www.dailytech.com/iPhone+6s+Focus+Pixels+Are+Already+...


They do. iPhones have used them since iPhone 6 and I think its common among other manufacturers as well in the high-end range of smartphones. But number of AF points it's still small and there are limitations due to the sizes of the sensors.


When I bought my Sony in 2012, it felt obvious to me that cameras with mirrors are a dead end.


Don't Canon and Nikon make pretty good mirrorless cameras too?


Not really. Olympus, Panasonic, Fuji and Sony have been good in this space. Canon and Nikon have been too afraid of cannibalizing their DSLR's to produce decent mirrorless cameras.


They came out with pretty gimped and disappointing products (sorry if someone's feeling offended) because they are too afraid of having their DSLR market segment disrupted by a decent mirrorless.

It really feels like a half-hearted effort, more to tick the "Mirrorless" checkbox in their product offering than to produce something compelling.

I'm not a huge fan of Sony, but I respect quality of this product and the effort they put in it despite having a DLSR line as well.


Canon have four mirrorless cameras with APS-C sensors (the M10, M6, M5, and M3). Canon don't have a full-frame mirrorless camera.

Nikon's mirrorless range is the Nikon 1, with 3 cameras which all have sensors well below APS-C spec.

So yes, they both make mirrorless, but neither makes a full-frame mirrorless.

[Edit: corrected the reference for the M6, which I initially referred to as having a sub-APS-C sensor. HT to ianburrell for the correction).


The EOS M6 has an APS-C sensor. In fact, it has the same sensor as M5.


My apologies, you're quite correct. I must have misread the specs - I'll edit the post to reflect that. Thanks for the correction!


Not really. Canon mirrorless is ok, I suppose, but very much a "also-ran" and "too little, too late" in the very competitive market. Nikon mirrorless are just not very good (too small sensor for a start..)


I have a Nikon 1 and I'm pretty satisfied with it. Key features for me were small package size, low weight and fast shooting (10/20fps with phase-detection autofocus). My use-case is being able to take some decent bike-action pictures with a camera that easily fits in a backpack. For other usecases the offerings from the other brands might be a better fit.


Canon's EF-m lenses are a fraction of the cost of Sony's. Sony have been pushing price points for a while to make sure they are at the top of the range, just slightly below boutique manufacturers. Meanwhile canon has a lot of experience building to a price point ... Interesting to see they chose to go down that route with their mirrorless system.


Nikon and Canon dominate the pro space for more than just the tech specs of their products. The support is amazing - check out this blog article to see. I thought B&H was close to photographers heaven but I've never seen anything like this.

http://blog.jeffcable.com/2016/08/a-very-rare-look-inside-ca...

Producing the camera that has the best specs doesn't necessarily mean that pros will be using it. (Depends on the size of the gap of course)


While 20fps makes nice headline, it is imho the least interesting spec of this camera. Some things I find interesting:

* Low light performance and dynamic range. Sony bodies have traditionally been good at this (see for example https://vimeo.com/99893160), I hope the trend continues.

* Video features. They say 4k full frame video, which sounds nice, but subsampling the sensor inherently comes with some compromises, which might be even exaggerated in 1080p mode.

* There is more to video than just resolution; does it have any high-framerate modes, what sort of video formats and color profiles does it support etc etc.

* The 5 stop equivalent image stabilization sounds impressive. Admittedly I haven't followed the state of art that closely, but I imagined IS being typically closer to 2-3 stop eqv.

* 1/32k shutter speed seems also quite fast. I wonder what sort of new photos such fast shutter speeds enable.

* Wasn't it Sony that "innovated" a lossy compressed RAW format? What sort of impact does that have on this camera?

... and probably some more.


> They say 4k full frame video, which sounds nice, but subsampling the sensor inherently comes with some compromises, which might be even exaggerated in 1080p mode.

They don't necessarily have to subsample, they may be able to supersample. I believe Panasonic's GH5 does this.

> does it have any high-framerate modes, what sort of video formats and color profiles does it support etc etc.

Full specs, including shooting modes, are here: https://www.sony.com/electronics/interchangeable-lens-camera...

In terms of high-framerate, it doesn't have anything for 4K but goes up to 120fps in 1080p. Can't see anything about chroma subsampling or bit-depth other than it only outputting 8-bit 4:2:2 through HDMI.

> Wasn't it Sony that "innovated" a lossy compressed RAW format? What sort of impact does that have on this camera?

Yep, though it appears that like the A7RII, you'll be able to disable it. It seems that doing so will roughly halve the number of frames you can take in a single burst and drop the max capture framerate to 12.


> * 1/32k shutter speed seems also quite fast. I wonder what sort of new photos such fast shutter speeds enable.

You can shoot with wide apertures in direct sunlight without using ND filters. Fuji has had this for years now, with much more rolling shutter of course.

Now that I wrote that out, doesn't sound like much. Still, it's been nice not to play around with the filters.



> an Ethernet port

!!!


Yeah, there can be a lot of bandwidth required. RAW images at 24.2MP are around 30-40MB (https://toolstud.io/photo/megapixel.php?width=6016&height=40...) and at 20FPS you're above 1Gbps (which a crowded wireless network certainly can't handle).

Add those bandwidth requirements to some of the real-time workflows professionals engage in today (see http://www.imaging-resource.com/PRODS/sony-a9/sony-a9A.HTM and the comments around 11:53) such as:

"first Sony camera with an ethernet port. Have to be real time. Shows, presidential debates, every shot I took went right out onto the network as soon as I shot it."

and

"for major UFC events, it’s vital to be able to do a live workflow, where images are constantly going back to an edit station and go out to the world immediately. Not only the ethernet, but the wireless is key for social media outfits all over the world."

and ethernet makes sense.


usb 3 is 5Gbps, thunderbolt is 10Gbps, thunderbolt 3 is 40Gbps. i don't think it makes sense to put ethernet ports on anything smaller than a rack blade.


They can also only go 5m, 3m and 3m, respectively, before interfacing to a computer (which then uses ethernet to go somewhere else anyway).

Ethernet makes sense if you consider that images are going straight from the camera to the control room (which is hundreds of feet away, and possibly parked outside in a truck), and that there's likely already network infrastructure (switches and cabling) in place for dozens of other reasons.


If you're suggesting they went with a USB or TB ethernet adapter instead, think about the complexity of supporting the numerous available NIC chipsets on something like a camera...


There is a Linux inside Sony Alpha. No problem with drivers :)


I do. It's increasingly common to have a rolling NAS on film sets and being able to hook up the camera and storage with an ethernet cable is a no brainer for many productions. Time is money and video workflows have historically been a logistical nightmare. Generally when you're shooting narrative on a pro camera you have to stop every 20-30 minutes to swap media. I would much rather string a cable and have one less technical person and two more people in the art department for the same money. Media management is a huge bottleneck, not to mention a source of continuous low-grade anxiety.


Ethernet provides (close to) the advertised bandwidth without any fuss and is compatible with everything. Contrast with the others you listed.


Sony is better at being Apple than Apple is.


If we imagine for a moment that it were 24 or 30fps continuous- could that output be used for video as an alternative to the designated video modes? What would make the results different?


Yes. Doing so would put the files in the same class as the CinemaDNG output by Blackmagic Design's cameras or RED's R3D.

The difference is similar to the difference between JPEG and RAW in stills. You get a lot more flexibility in post and can usually capture a little more dynamic range. There's a video comparing RAW video to H.264 here: https://www.youtube.com/watch?v=jkSYIzCgdIk


Yes, absolutely. The difference would be in the resolution (stills are typically way higher than video), and the fact that you'd need to do your video playback offline. You could use it for video now at 20fps (anything over 18 is adequate if you don't mind it looking a bit stylized) but you're likely to run into data bottlenecks...or maybe not, Sony has historically been pretty good at handling high data rates and the removable media themselves are constantly improving sustainable write speeds.


Each frame would be 6000x4000 pixels -- 6K with a 3x2 aspect ratio.

20 fps is almost there (playing at 24fps is a 12% speedup), but how long can you practically record at that speed?


The image buffer is 241 pictures so it'd be about 12 seconds of recording at 20FPS.


The fact that 24/30 < 60fps, which is the video frame rate (and autofocus rate) in 4K video mode.


If they finally made auto-focus acceptable, I am willing to dump D750 as my main hyperlapse-creation tool and buy Alpha 9 for travel. Mirrorless always had issues with focus, if the improved quantum efficiency of the sensor allows better focus, they have a winner.


Has Sony fixed their ARW raw file compression story yet? Last I checked, you had a choice between a huge uncompressed raw and a lossy compression technique susceptible to posterization artifacts on high-contrast vertical edges.


I will never forgive Sony for the rootkit they installed on my computer.


That was 12 years ago. The only reason to mention it now is to signal your nerd power level; if you actually care about this you're being absurdly petty.

Just for context, Pacific Gas and Electric (the primary power utility firm in northern California) killed 8 people and destroyed an entire neighborhood a few years back due to their failure to repair a gas pipeline that they knew to be defective.

An unwelcome root kit on your computer is a Bad Thing that it's reasonable to complain about at the time it happens, but as injustices go it's pretty minor. If you're still holding a grudge about it over a decade later then you've been enjoying a very sheltered life.


One complaint I read about Sony mirrorless is a greater tendency to have dust problems due to lack of a mirror. Anyone familiar with that issue and know if it is a real problem?


Lack of a mirror shouldn't affect that; the fact that it is shutterless (which doesn't require being mirrorless; there have been shutterless DSLRs) might.


Where does the A7r II / A7S fit in with this? Are they considered a prosumer version of this camera? And if so, what makes this more professional, the FPS?


Yes, the A7 models seem to be more geared for prosumers or non-sports/wildlife professionals (e.g., for portraits I'd still lean towards the A7Rii).

The A9 is more "professional" because of its dual memory card slots, supposedly much better AF, FPS, battery life, and controls (joystick).


Not an exact parallel but I see the A7R as the MD Mark III and the a9 as the 1DX.


That's interesting considering so many professionals use the Mark III. I recall seeing an article that the NYTimes staff all used Mark II's at one point.


Wow. That's an impressive spec list for a body this size.

I don't see anything about how weather sealed it is and the press release doesn't mention it either.


I think the press event is still in progress, we'll be finding out more as the day goes on.


I'm excited for the A9"S" I guess, the super low-light version of this.

Can't afford either one though, but I can dream.


So what exactly does Sony have to do to become king of cameras? This is a very good argument.


Well, Sony has been the "co-king" of consumer P&S cameras for a long time, but those are in steep decline due to ever increasing capabilities of smart phones, where Sony (unlike Canon or Nikon) continues to make money with their Xperia line.

On the high end, they lack one key "ingredient" in my opinion which can be best described by one word: ecosystem. Ask any serious Nikon user and they'll show you a $15K collection of lenses, flashes and even old film bodies with high sentimental value to them. They will also talk for hours about "Nikon approach to color" if you'll listen. Competing against this takes time: Sony needs more lenses, more famous photographers walk around sporting their gear, consistently communicated "vision", etc.

This can also be a tough cultural problem to overcome. I've been shooting Canon on and off most of my life, Nikon gear is very similar in that it feels like a computerized camera system, i.e. a computer is an add-on to an excellent camera helping you take better pictures. Fuji cameras have the same feel. But every time I try Sony it feels like mm... hard to explain, maybe like a "computer which happens to take photos"? Very subjective, of course, but since you asked. ;)


I've tried the fujifilm mirrorless cameras, and they've also had that feeling of portable camera with a computer attached. I've personally always loved the feeling of a computer engine driving the sony camera (a7 evf is wonderful).

If mirrorless is the future, and partially what allowed Sony to make 1/32000 possible, then does that mean Canon/Nikon are playing catch up?


Hard to say. My guess is that an EVF is a trivial add-on and both Nikon and Canon are capable of executing well and would have added it to their SLRs if they wanted. Why they're clinging to the mirror... I have no idea. I certainly prefer optical viewfinders but I can't claim I'm in the majority.

Frankly, the modern photo equipment is just too good to even imagine a dramatic leap forward by one player. ISOs have skyrocketed, dynamic range is amazing, AF is fast and intelligent, etc... One major area worth improving is the weight IMO. If someone defeats the laws of physics and produces an optical equivalent of 24-70mm f2.8L mounted on a 5D, but at 30% of the weight/size, it would be an instant hit.


Greater lens affordability/compatibility. If they offered compatibility with Canon glass they'd be unstoppable because there's a lot of that about.

For video Sony is really pulling away from the competition. Outside of niches like sports and nature videography autofocus isn't nearly as important for video as it is for still photography, and nor are super-high-quality lenses - as long as the image is reasonably sharp people actually like the idiosyncrasies of older lenses in many contexts, and in any case it's common to rent lenses you need for a particular project rather than needing to have every option in your bag.

Sony has really been killing it with their low-light capability and ergonomics in recent years, and while you could point to other camera firms that do better in this or that specification area, the fact that Sony is a large global corporation that's very unlikely to go out of business in the foreseeable future is also an asset. I don't own any Sony camera gear myself so not being a fanboy here.


Lenses, they need killer lenses people are willing to switch systems for.

That and better battery life.


Is this a successor to the 7-series cameras, or a step above?


But 20 fps isn't that much. Why not 60 or 120?


> But 20 fps isn't that much.

20FPS is insane on a 24MP full-frame camera. Each RAW is 6000x4000.. The image buffer can handle 241 pictures, so you can basically capture 12 seconds of 6k video.

To give some context, this camera can easily record 120FPS 1080P video with full autofocusing. It can record no-crop 4K video which means if you take a video of a scene, you can grab a full 24MP still from the video. 1080P video has 2 million pixels, 4K video has 8.3 million pixels, burst mode on this camera has 24 million pixels per still.


Because the data rate on 6000x4000 pixels uncompressed times 60 would be insane? 4k video is only 4096x2160.


Impressive hardware indeed, but price is prohibitive (at least for me!) right now: usd4500
