Does not work with PC-E Lenses

By Paul
Rated 1 out of 5
Date: 2025-04-10

Despite the published information this adapter does not work with the Nikon PC-E lenses. Tested with 24/45 and 85mm and on 2 Sony A 7Rii bodies. It doesn't connect and allow the electromagnetic shutter to engage. Also tested with the 105mm f1.4E lens and that doesn't work either. To B&H's credit they issued an RMA immediately.

No autofocus

Pretty limited in range. Autofocus does not translate well. If you dont have a lot of Nikon F lenses, not worth it.

I would like to use this adapter to mount a Sigma 4.5mm f/2.8 EX DC HSM Fisheye to a Sony A6500. Hs anyone tried this to know if teh lens will AF and communicate properly with the camera?
Asked by: Michael J
We have not tested this specific combination, but there is a good chance the lens's AF will function since it has an Hyper Sonic Motor (HSM).
