That lens has gorgeously clean design. I'd bet it was a good one optically too...

Nice.

How did you mount it on the Nikon or it can not focus to infinity ? As I know there is a registered difference between the two mounts (Topcor's Exakta bayonet - http://www.camerapedia.org/wiki/Topcon#Exakta_lens_mount - and Nikon's F mount), 44.7 exakta vs. 46.5 Nikon.

It looks like they shortened the mount by a couple of mm when they removed the back plate of the Topcor and removed the auto-linkages, which should be enough to match the register distance of the Nikon and give it infinity focus.

A very professional job.
