2016-05-26, with Sony A7 and Contax G Carl Zeiss 45mm f/2.0 Planar.

The 45mm Planar is actually a 47mm, while most 50mm lenses are a bit slightly above 50mm in reality.

To me the separation between the foreground and background is maybe a little more pronounced for this kind of distance than to be expected and the lens is not a super “fast” one.

Also of note, the left and right corners of the background are more sharp than the background in the center. A good example of a lens with strong field curvature, which is bad for photo tests and brick wall photos, but in my opinion very desirable characteristic for portrait and other ‘bokeh’ sujets.

Also I think the lens has some visible barrel distortion here (but is not so strong and hasn’t ruined any shots so far:). By looking up, distortion on the corner is -1%.
