Rokkor MC to Nikon F Remix

thingiverse

Remix of https://www.thingiverse.com/thing:4099515 to improve the fit of Rokkor MC lenses and to index the lens to the adapter. I had to remove at least 1.5mm of material on the Rokkor side of the original design to get my lens to fit. This version cuts away some material from the inner tabs and expands the adapter diameter as a whole by about 0.5mm. Both fits will be slightly tight at first and may require some fine adjustment with a file, but this ensures that the lens will be secure to the adapter and the camera. Because Minolta's MC mount has a shorter flange to focal plane distance than Nikon's F Mount, lenses will not be able to focus anywhere close to infinity. It is better suited for macro photography or dreamy bokeh photos. The furthest I could achieve on my DSLR was about 0.5m/1.5ft, but the results were worth it (see the sample image of our cat taken with the infamous Rokkor PG 58mm f/1.2 wide-open). Thing photo was printed at 0.12mm layer height for better tolerances. This object was made in Tinkercad. Edit it online https://www.tinkercad.com/things/8VZJlMkoCUa
