From what I gather the distance between the left and right lens will be less than an inch. Technically it’s still stereo, but don’t get your hopes high.
They didn't say much about it but hopefully they can infer enough to do a good job. You can already do mildly ok fake depth maps from a single image. I also would like to know if this is going to be somehow locked down to Apple Vision or a format we could use in a Quest3 or other VR headset.
180 camera makes more sense at this stage. 360-degree cameras on a phone would be weird when recording with the phone in hand. It would be better on a tripod, but I think Apple is trying not to complicate it unless professionals want it.
