The Mamiya 24mm fisheye doesn't allow AF with the AFDii, which is fine. What I'm wondering is if I use it on shutter priority (tv) mode, will the camera automatically change the aperture, or because since the lens has an aperture ring this is not possible? Thank you.
If that's the Sekor C one (which I also have), which I think it is, then I think no is the answer. You need to set the aperture before shooting.
