Focus Stop Ring for Rokinon 14mm Lens

thingiverse

The Rokinon 14mm is an excellent night photography lens, but like all lenses it can be difficult to achieve a good infinity focus in the dark. With these rings (you will need to print two of them) you can set infinity focus in the daylight, then tighten the rings to prevent focusing past infinity. You will need an M2 x 16mm screw with nut & washer for each ring. Added a stronger upgraded version, _v2.
