Leica 28mm f/2 Summicron-M ASPH on Panasonic S1R: Evaluating Applicability for Environmental Portraiture
See my L-mount mirrorless wishlist
This page is an exploratory probe into whether the Leica 28mm f/2 Summicron-M ASPH can deliver good quality for close-range environmental portraiture when focused somewhat off-center. Used that way, the issues of field curvature and corner to corner performance are largely of little import. The issues of bokeh and color shading and secondary color are of perhaps more interest than sharpness.
In diglloyd Leica M:
Includes images up to full camera resolution, but also 24 megapixel images downsampled from 46.7 megapixels. The 24MP variants are the same resolution as what can be captured on a Leica M240 or Leica M10, helping to provide perspective versus the rangefinder option.
