spydrxx Posted March 3, 2024 Share #3 Posted March 3, 2024 Just don't mount a collapsible lens in the collapsed position. Lots of discussions on this topic. 2 Link to post Share on other sites More sharing options...
scott kirkpatrick Posted March 3, 2024 Share #4 Posted March 3, 2024 The net seems to be: mount it while open, then gently collapse it. Possibly the dangerous step is to rotate it while installing it collapsed with the rear element waving about. But that's a fairly soft, but glowing lens. Special purpose, primarily. Wonderful (and appropriate) on film. I've used one on an M2 since the late 1960s. 1 Link to post Share on other sites More sharing options...

david strachan Posted March 3, 2024 Share #6 Posted March 3, 2024 (edited) I've had a collapsible Summicron for about 10 years now...love it. I don't worry about how its fitted, as it's always extended. Never collapsed.. Unless you need to make the system very slightly smaller, perhaps to put in a brief case, can't see the point of making the lens shorter.

Photoworks Posted March 3, 2024 Share #7 Posted March 3, 2024 Advertisement (gone after registration) This was a question often asked to leica's product manager when M11 came out. They say yes and no, to check the different lens charts. The modern construction of sensor, glass, and shutter pushes the material forward, limiting the available space. Not every collapsable lens can be closed fully. Link to post Share on other sites More sharing options...
