Canon EF Camera to Nikon Microscope Adapter

thingiverse

First published recently, this adapter allows Canon EF lenses to be mounted on an old Nikon lab microscope. Based on the maker's earlier EF Mount design, it can be printed without glue or heat. While it is a mechanical adapter with no optics, focus is achieved through the camera lens. Camera aperture is determined by the microscope lens, so only ISO and shutter speed can be adjusted. A comprehensive tutorial, along with images and video, is available on the creator's website.
