Minolta SG MC Rokkor 28mm f3.5

     This was my first experience with the W Rokkor SG 28mm f3.5.  I tested it on a EOS M3 body with a Fotasy adapter.  It has an all metal body.  Like many f3.5's it jumps from f3.5 to f5.6.  It does offer 1/2 stop clicks from f5.6 up.  Focusing was not difficult but not nearly as effortless as with a Zuiko lens.  Focus dampening is smooth and light.  Sharpness is acceptable at f3.5 in most situations.  At f5.6 it tightens up a little bit.  Contrast is good except for backlit situations.  Flare causes a framewide reduction in contrast. Corners are reasonably sharp.  Vignetting is noticeable at f3.5.  Color rendition is typical Minolta.  It's a tad flat but accurate.  Black and white rendition is excellent.  See the example below.  Red on red is difficult for lenses to render in b/w.  This lens handled it with ease.

This lens will fringe in harsh lighting at f3.5.  It will be noticeable but easily correctable.
