john_hartung1 Posted August 2, 2003 Share Posted August 2, 2003 Should LF lenses be stored with the shutter cocked or sprung? Thanks for your help. John Hartung hartung@post.harvard.edu Link to comment Share on other sites More sharing options...
leonard_evens Posted August 2, 2003 Share Posted August 2, 2003 My guess is that the shutters should not be cocked except when you intend to use them, but modern shutters are quite robust and probably wouldn't be harmed if inadvertently left cocked. What would be the advantage of keeping the shutter cocked? Link to comment Share on other sites More sharing options...
ling_z Posted August 2, 2003 Share Posted August 2, 2003 Take a look at a previous thread: http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=003Cqk Link to comment Share on other sites More sharing options...
michael_a._smith1 Posted August 2, 2003 Share Posted August 2, 2003 Never cocked. Keep the tension off. Michael A. Smith Link to comment Share on other sites More sharing options...
alex_hawley Posted August 3, 2003 Share Posted August 3, 2003 Springs can weaken over time if they are kept under tension. The weakening is slow, maybe taking a few years, so one usually doesn't notice it until its too late. That is the reason why shutters are best kept uncocked.

john_hartung1 Posted August 3, 2003 Author Share Posted August 3, 2003 Thank you all. To my satisfaction, as is so often the case, Bob Solomon posted the most convincing answer in the thread referenced by Ling Z -- shutter uncocked (sprung) with aperature set wide open and exposure at "T" (and for longer term storage, in a plastic bag with a dessicant).

jonathan_bundick Posted August 3, 2003 Share Posted August 3, 2003 Uncocked, and set to T. Link to comment Share on other sites More sharing options...
