I was cleaning out a darkroom cabinet the other day and found a Komuranon-E 75mm f5.6 enlarging lens. I can not recall why I bought it or how long I have had it. It appears to be well made and is in good condition. I did an internet search which was not that helpful. Opinions ran from it being a piece of crap to it being better than Leitz, Schneider, Rodenstock or Nikkor. Some said it was the worst lens they ever used and some said it was the best lens they ever used. Has anyone here ever actually used one?
