G 896 # 9 Summaron 28mm f5.6 LTM by T&T and Mr B Abrahamsson, on Flickr
Summaron 28mm f5.6 Ltm. This is with the original Summaron 28f5.6 - stopped down to f22. Distinct edge darkening but remarkable sharpness across the image. If the "retro" version could keep the resolution and lessen the edge darkening - it could be an interesting lens. Today we are less constrained by 'slow" lenses as the digital M's can handle ISO's up the 2500 or even more with no significant loss of quality.
