Here's a posting to the rec.photo.equipment.35mm newsgroup which continues the discussion of the Keppler article. "I have to side with Keppler on this one. I own an early Pentax SMC 50 f/1.4, same optical formulation as the Super-Tak, and two versions of the Summicron 50 f/2.0. The Pentax lens holds its own. At f/2 the older (late 1950s vintage) of the two Leitz lenses is a few hairs sharper, the later (1980s) Summicron adds a contrast boost to the equation but the SMC wins the smooth bokeh award. In terms of flare resistance at wider apertures the newer 'cron is best, followed by the SMC and then the older 'cron. From f/4 on down in a blind test I couldn't tell you which lens took which photo. FWIW in my experience the 50mm lens with the most distinctive and pleasing optical "signature" is the old Zeiss f/1.5 Sonnar. Just last week I looked through a friend's portfolio and picked out five b&w prints that had the Sonnar "look." I was right all five times. :-) -Dave-" * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * <>< <>< <>< <>< <>< <>< <>< <>< <>< <>< <>< <>< - This message is from the Pentax-Discuss Mail List.
