Lines: 12 In response to the request for an old, non-AI mount Nikon PC lens: It turns out that Nikon designed the new, non retractable aperture fol- lower for the FG and FA in such a way that it clears some non-AI mounts. (The retractable finger of the FE causes no problem, of course). In particular, I have both an FG and an FA and use my 35mm f/2.8 PC lens (dating from around 1968) on both. Of course, it is non-AI. However, be forewarned: the PC lenses do not work in AMP mode on the FA since they cannot tell the camera their maximum aperture. As a result, there is no way that the camera can "correct" its AMP program for light falloff. So, both these lenses must be used in manual mode.
