Samyang 135mm aperture test

Description

Did some tests of my Samyang 135mm f2.0 lens.

The majority of the image stayed perfectly sharp with any aperture setting I used.

The corners were interesting. (I picked the worst looking corner, they were all slightly different) At f2.0, the stars looked a tiny bit bloated and fuzzy. As I stepped down the aperture, the stars started to look sharper, but elongated in shape instead of round.

I will conclude as many others have. This lens is perfectly useable at f2.0, but I think the sweet spot is f2.8.
