Closest Focus at f/4

f/2: A little soft with low contrast and quite a bit of chromatic aberration.
f/2.8: Sharpens up quite a bit with decent contrast and very little chromatic aberration and nice color.
f/3.5: Very sharp with good contrast and very little chromatic aberration.
f/4: Very sharp with a hint of chromatic aberration.
f/8: Very sharp with great contrast and color and no signs of diffusion until f/11.

A fair bit of vignette and is basically gone by f/4.5.

The bokeh is fairly nice and not too distracting but not worth getting excited about.

Flare and Ghosting
Very evident flare at all stops and quite a bit of ghosting. Ghosting has nice shape and color at larger apertures.


A fair bit of Barrel Distortion and more then average.

Want a fantastic 55mm lens at f/2 and don’t mind manual focus then this lens is a bargain. The lens is a little soft at f/2 with a fair amount of chromatic aberration. If you don’t mind stopping it down a bit then this lens is very sharp, fantastic, and is not too hard to find. One thing you need to watch out for is that the elements can turn a yellow tinge over time but this is really easy to get rid of just by simply shining a UV light in it for a little while.

The lens is tiny and feels great in the hands, handles really well and is simple to use.
