FotodioX Pro Lens Mount Adapter for Exakta/Auto Topcon Lens to Canon EF-Mount Camera

When using this adapter on a Canon EF-mount to Nikon Z adapter, the flange distance would be the same as one gets when using this adapter directly on a Canon camera. So it will perform equally well on your Nikon Z7 II Mirrorless Camera as it would perform on a Canon EF-Mount camera. However, I would suggest using a different setup. The FotodioX uses an optical element to compensate for the flange distance difference of the Canon EF-Mount. With the Z7 II this optical element is not necessary and a direct adapter such as the KIPON Lens Mount Adapter for Exakta-Mount Lens to Nikon Z-Mount Camera would be a better option, BH #KIEXAKTANIKZ (https://bhpho.to/3uC9oiG). With the Kipon one is not adding an optical element into the mix, and so the lens can perform as it was originally designed to perform.

No lens adapter in the world changes a lens's focal length. If it is a 50mm, it will be a 50mm forever. What does happen when the sensor changes, or as in this case, a very slight extension is made by the adapter's conversion lens, is a change in field of view. In this instance, the adapter is making up for the 0.7mm difference in the two lens mounts. What will happen is a tiny widening of the field of view as compared to what you would see on an regular Exakta/Topcon camera.

Yes, the FotodioX Exakta, Auto Topcon Lens to Canon EOS EF Camera Adapter allows infinity focus.
