However, except for aspect ratio, everything else would require some non-trivial work from the developers, unlike roll, which is simply restricted to mapping a button to it.

Real-time FoV modification is fairly trivial in most game engines.

Aperture and focus are sometimes going to be fairly simple to enable for a photo mode if a game already uses in-engine DoF.

Sensitivity and shutter speed might get tricky, especially if you want to account for camera motion, and who knows if it'll to interact nicely with DoF in screenshots.
Lens type could also get weird, though the game could render screens with perspective projection and reproject to get other projections (Destiny with 360-degree equirectangular screenshots would be nice), though that's a pretty high request.
