I'll try to retrieve them but all in all my asph v1 is sharper at f/2 than both my German and Canadian v4. It has also less focus shift, curiously enough. Aspherical element is able to reduce focus shift, theoretically, since focus shift is a form of the spherical aberration. Though lenses with aspherical glasses does not essentially guarantee the absence of focus shift. Link to post Share on other sites More sharing options...

What i find curious is complains about focus shift aiming at the 35/2 asph v1, given that mine has none, but not the 35/2 v4 although it is obvious, if not huge, on both my German and Canadian v4 copies.

lct Posted August 6, 2023 Share #106  Posted August 6, 2023 German 35/2 v4 @ f/2 on M11 (FF & crop). Just a snap to show the moderate acutance of the "KOB" at full aperture and its typical bokeh. For more acutance and smoother or more gaussian bokeh there, better choose a Summicron 35/2 asph v1 (no experience with v2). Welcome, dear visitor!

costa43 Posted August 11, 2023 Share #108 Â Posted August 11, 2023 For me there is a significant difference when I zone focus on a film camera as opposed to digital. On digital I use a stop less on the scale vs my aperture. Film is a fair bit more forgiving. 1 Link to post Share on other sites More sharing options...
