I used it with an arducam for a personal project. I works perfect!

Good "fisheye" (really wide-angle lens). Has typical barrel distortion - as expected. I used for an AllSky astrophotography setup. One very nice plus was that the inside and outside of lens is black - which reduces reflections in glass or, in my case, acrylic dome that it was in. Not the sharpest but worked great for point light source - i.e. stars :) Great value for the price!! Recommended.
