Sharpness

f/2 Nicely sharp for wide open with only a little softness, and a little chromatic aberration and pretty good contrast.
f/2.8: Sharpens up a ton with fantastic contrast and almost no chromatic aberration.
f/3.5: Very sharp.
f/4: Sharper yet.
f/8: The beginning of a little diffraction.

Vignetting

There is a little bit of vignetting at f/2 and quickly clears at f/2.8 with only a hint at f/3.5 and gone by f/4

Bokeh

The blur is pretty decent and only a little distracting but because this lens is contrasty it seems to highlight some bokeh which can look a little distracting.

Distortion

Amazingly straight with very little visible Barrel Distortion.

Out of 5

This lens is great, sharp when shot wide open with only a little chromatic aberration. Built like a tank with a retractable lens hood, this heavy but solid lens feels amazing to shoot.
There is very little vignetting but more barrel distortion then I had expected.

This lens still fetches for a few hundred dollars and I’m not convinced it’s worth that. However it is one of the best 50mm f/2 lenses out there as expected. I would just have trouble spending this much money on a manual focus f/2 lens when you can buy an auto focus f/1.4 lens for the same price. But if you want one you can’t go wrong. This lens is fantastic and built to last forever!
