Rokinon 14mm filter holder for APSC camera (Z filter)

thingiverse

I built this filter holder to use with my Rokinon 14mm ultra wide angle lens on my APSC cameras. Is buit in 5 parts. a semi cilinder that sorround the actual hood of the lens, to prevent reflection from behind in the filter, two actual filter guide (you must to glue this to the semi cilinder), and two litle pieces to hold the screw (headles). There is a space for a 8mm nut, you must glue this too. This works fine with an APSC camera. In full frame cause an ugly vigneting. Warning. I made this again after breaking my old pringting, but in Blue PLA. i dont recomend using light o other color than black, because will cause reflections in your filter and a nasty artifact. i recoment sand the inner part, until no reflections can be seen. Instructions i recomend test a few layers of the semi cilinder to adjust scale. after that print the pieces, glue the filter slots to the main (for the wide side, centered) and add the bolt and nut. if you prefer, cut the head of the bolt, and add the plastic nobs. Update(20160218): use sandpaper in the the interior for less reflections, use black or most dark plastics, minimize the filtered and traslucent light from the sides
