Title: TV mode on 645 afd ii
Post by: ben decamp on October 06, 2007, 02:04:32 am
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.

I don't have the lens but the 120mm macro has a switch to change between full manual and auto aperature (manual focus only) modes so without the switch I think it is full manual only

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.
