Extremely Sharp when stepped down, light in weight, very small compact built compared to other 50mm lenses, With the use of the Leica M39 adapter makes for a ver compact option for the Sony A7III, it has a good dynamic range, the color rendition is amazing, the black and white renditions are rich and with a wide range of tones of grays, it is cheaper compared to its original cousin formula Carl Zeiss Sonnar, the breathing is acceptable and it does produce a very emotional look, with a magic 3D pop and smooth blur in non focused areas

Weaknesses:

When shot towards a light source looses a lot of contrast real fast as the source is stronger but it has cool star gosts when stepped down and the flares and glares are pleasing and good looking when they apear. When fully open only the very center of the image is sharp, and it suffers from a glow, the rest of the image will have that glow all over softness and chromatic aberration. It also suffers from a little radial distortion easily corrected in post. 

Comments:

Love this tiny lens it has a lot of character, people ask constantly what kind of lens is it because of the shinny silver look it is powerful and compact, with a maximum aperture of f/2 it is a balanced lens but not as fast as a f/1.4 or f/1.2 though it will give an awesome 3D pop and cool separation with a soft creamy delicate bokeh.

- very good black and white noir tone

- little sweet color low contrast

Weaknesses:

- cloud 

- when direct to light some detail is missing.
