I purchased this to do astro photography because it was rated at f/2 which would give me two full stops more light than my Fujifilm XF10-24mm f/4 zoom. However I found that at f/2 it was quite soft at the edges and there was also some coma and slight CA away from center.

    Soft At The Edges F2

Sigh! While I expect quite a bit of sample variation with Samyang/Rokinon lenses, I was hoping to get a sample of the 12mm f2 that I could use when shooting JPGs (and video) with three tries, but I did not find one I wanted to keep.
