tappan Posted March 4, 2013 Share #21 Posted March 4, 2013 Advertisement (gone after registration) Hello after all these years :-) Does the collapsible M mount (not LTM) collapse safely into an M9? Thanks, Mark Link to post Share on other sites More sharing options...

jaapv Posted March 4, 2013 Share #22 Posted March 4, 2013 Which one? Not the old 90, for the rest it has been discussed very often: Mount and dismount extended and collapse safely. Link to post Share on other sites More sharing options...
Universalb50 Posted March 18, 2013 Share #23 Posted March 18, 2013 I had a collapsible summicron with scratched front lens polished and recoated by a well regarded repair service here in USA. It is very nicely cleaned and coated, but the images from it are very poor, much worse than from my late version summicron or the collapsible summicron pictures shown on this thread. Does polishing and recoating of a lens typically make it much less sharp? Link to post Share on other sites More sharing options...

Does polishing and recoating of a lens typically make it much less sharp? No, but not calibrating the lens afterwards correctly does! I have had a similar experience unfortunately.

Does polishing and recoating of a lens typically make it much less sharp? I posted this on another thread, but wanted to show you since you are having this problem. Since this is a new lens for me, I got this 50mm Summicron collapsible from 1955, last week, can you tell me if this is sharper than what you had before the cleaning? Welcome, dear visitor!
