scott kirkpatrick Posted November 27, 2015 Share #4 Posted November 27, 2015 I think I could live with that. How does it look with distant point light sources in a night shot? scott Quote Link to post Share on other sites More sharing options...

ramarren Posted November 27, 2015 Share #6 Posted November 27, 2015 What did this lens perform like on film? That's the reference standard, for me, so I'd need to see a similar exposure on 100 speed film to evaluate whether the SL is adding anything to the lens rendering or whether it's just what to expect with the lens. I don't have the APO Summicron-R 90mm, I have the older Summicron-R 90mm. Comparing to an exposure quick-test with ACROS 100 at all apertures, the lens behavior seems the same, but I don't have anything to evaluate coma against specifically. Maybe I'll shoot some streetlights tonight. Quote Link to post Share on other sites More sharing options...
