Different camera systems are best at different things. Are you shooting sports and action and wildlife photos? Are you into portraits? Shooting video? Dark clubs at night? Street photos? There's lots of types of photography. For me I'd personally look more into Fuji and Nikon stuff, but there's a lot of options.

I'd second looking more at the glass you'd need to get than the camera. The camera body you spend 1000-2000 or more on today will be available on eBay for relatively cheap in 5 years, but good glass will retain its value and use for decades. There's 20+ year old lenses that are better for some tasks than any modern equivalents: they just lack a few modern features.

Depending on your type of photos, look into spending more of your budget on lighting. You can do more with a junk camera and Lens and great light than you can with poor light and a great camera and lens.

Camera bodies come and go fairly quickly, which is why I tend to invest more in glass.

If you start paying over say $1000 per lens, they generally retain their value. What's more, a quality lens on a mediocre chip is going to look much better than the inverse. That's my experience anyway.

That's what I would think. Just keep swapping out bodies to keep pace with the tech

This is an odd question. Unless someone's a professional photog, they're going to pick an amount of money they feel like spending on a camera and then do that. If that's less than thousands of dollars, they're not going to be getting an "ultra high MP camera".

The "best digital camera" is the one you can afford. That said unless you're a true enthusiast spending £3-5k on a top end body it's pretty pointless, might as well go for something along with the 70D or d7100/7200.

I think it's a given that anyone asking about cameras that high end is spending that kind of money.

I brought it to HN from a different angle. Most photographers crop and downsample to help them establish proof of copyright (since they don't have negatives). With 4K screens becoming commonplace, it seems like they're about to lose that arms race.

But even then most DSLRs are at least 20MP+ giving enough wiggle room to crop/manipulate the image and still have a high enough resolution to display on 4K devices.

I don't think it will be an issue for a good while yet and by that time I'm sure new bodies will come out to take advantage of it.

The one he was referring to in his post is 12MP.

I think the parent was talking about currently available models. The D90 quoted is from 2008, and nowadays even good compact/superzoom cameras can do useful 4k photos.

Yes - looks like from his followup he's going with a D750.

So, yeah, body swap. I guess the war continues :)
