p.1 #1 · KIPON Pentax 645-Fuji G Adpater question.
I recently got the KIPON Pentax 645-Fuji G adapter so I could mount a SMC Pentax A 645 120mm f4 Macro Lens on my GFX for scanning film.
The adapter locks into place on my GFX just fine but the lens is not locking in place on the adapter. It rotates about an inch and seems to hit a hard stop. There is a little metal tab on the outside of the adapter that can slide in/out a very small amount but moving that one way or another doesn't seem to do anything.
Does anyone know how the lens should be locking onto this adapter or if there's anything special I need to do? I tried to google this but I'm not finding much information and t he manual for the adapter is quite sparse.

It should just work. I use the Kipon with the Pentax 645 300 f/4 A* without issue. Might try exchanging it. Macro lenses can be weird, though. Have you tried mounting it with the focus ring at different positions, fully retracted versus extended? Or aperture ring at different positions, wide open versus closed down?
I had a Novoflex that was Contax C/Y to GFX and it worked with all my C/Y lenses except the 100 f/2. Sent it back and got a different brand that worked fine. Sometimes they don't design the tolerances to accommodate every variable.
