I am eagerly awaiting the arrival of a Zorki-5. The salivating doesn't diminish with experience. Tonight, on the following web site: http://home.att.net/~wayne.cornell/camera/zorkic5.html I found the following statement: "Several Z5 authorities warn that the camera can be damaged if the shutter is tripped without a lens on the body." Now with my rudimentary understanding of FSU LTM bodies - 8 FEDs and 3 Zorkis - this has me stumped. I mean, how does the shutter 'know' whether there is a lens mounted or not? Does anyone have any experience of this, and why is it so? :confused: Cheers, Peter.
