stu dall Posted October 10, 2006 Share Posted October 10, 2006 I received my recent lens purchase from ebay today (Schneider APO Symmar 150mm), and was giving it the once over to check that all was well. I turned the aperture dial a few stops, and then realised that the shutter was 'cocked'.What a plonker!I subsequently fired the shutter at all speeds, and everything appears to be working as it should. Have I damaged the shutter, or have I got away with it? Link to comment Share on other sites More sharing options...
leicaglow Posted October 10, 2006 Share Posted October 10, 2006 Maybe I'm not following Stuart, but changing the aperture on a Symmar, while cocked, shouldn't cause a problem. Link to comment Share on other sites More sharing options...
capocheny Posted October 10, 2006 Share Posted October 10, 2006 Stuart, Short answer... nope, it's fine! Cheers Link to comment Share on other sites More sharing options...
darcy_cote Posted October 10, 2006 Share Posted October 10, 2006 Oh, you did it now. Its broken, send it to me. I will pay the shipping. ;-) Darcy Really, you are okay. Enjoy the lens! Link to comment Share on other sites More sharing options...
big toys are better Posted October 11, 2006 Share Posted October 11, 2006 Well, I already have a nice and very light 150mm, but yours sure sounds like a nice unit when I'm not hiking. Unfortunately, the aperature and shutter mechanisms are only connected mechanically by the retaining rings within the lens, so busting one will seldom affect the other. But if still feeling guilty you could send it to me, I'd even double the shipping costs previously offered.... Link to comment Share on other sites More sharing options...

leonard_evens Posted October 11, 2006 Share Posted October 11, 2006 With all relatively modern shutters, you can change any setting with the shutter cocked without damaging it. That would certainly include changing the relative aperture, but in most cases you could also change the shutter speed. Whether or not that applies to your shutter, i don't know.

stu dall Posted October 11, 2006 Author Share Posted October 11, 2006 Leonard...you've just made me realise that it actually was the shutter speed that I changed, and not the aperture. From what you're saying though, I should still be ok. Stu. Link to comment Share on other sites More sharing options...
big toys are better Posted October 11, 2006 Share Posted October 11, 2006 Changing the speeds a few notches isn't a big problem with modern shutters, but is risky with some older shutters. However, I don't generally change mine more than a few notches up or donn even though the modern designs and their springs are nominally capable of going the full range without problem. I did make a small mistatement above-- it is the shutter unit that holds both the shutter and aperature mechanisms, but again, they are not mechanically connected. Of course, you won't be able to release the shutter if it is locked open for focusing.... Link to comment Share on other sites More sharing options...
