I am not sure whether you can input it though for non-coded lenses...
I'm guessing the new A7ii allows for specifying focal lengths since it has built-in stabilization. There's no way to do this with an A7r, though. Likely the same is true for the A7s and original A7.-Dave-
Hi Dave, you can input the focal length but Sony chose not to carry this info over into the exif data. It's only used as an input to the IBIS.
Figures…same goes for Olympus.
there is no way to register aperture on old Leica lenses but I think you can mark the flange and get some kind of feedback I think Check out Reid Report. A subscription service he does things like thisWith that said, I still don't think adopters know how to look or record anyway
