Hallo AQUILIAN, I thank you for the comment.
In next hours I will post a image from the same point of view taken with the Leica Apo-Summicron-M 90mm and a 200% comparison from Sonnar versus Apo-Summicron @ 2.8

I hope You would upload Apo-Summicron 90mm to compare it too :) This lens (Sonnar) has outstanding sharpness but I don't feel I've fallen for this bokeh. I wish to take shot with this scene and Carl Zeiss Jena Prakticar 1.8/80mm. I believe I am familiar with double gauss' bokeh more than with sonnar type, especially with this short telephoto focal length. But I am very currious about reasults of Apo-Summicron. I bet that bokeh and overall would be better with Carl Zeiss Sonnar G-mount :)
