I had been discussing the SL35E off topic on another thread and wanted to continue over here. I had an SL35E since 1984 and the shutter stopped working around 2002. I picked up two nice SL35Ms in the mean time and finally got around to getting another SL35E from Germany. The camera came in the mail today and I compared it closely to my broken one. The major difference externally is the presence of slotted screws holding the top. On the inside there are silver rivets on the shutter curtain, as opposed to black ones on the broken camera. Looking at the shutter mechanism from below, clearly the new-to-me camera has a more robust shutter. It is not the same. There are quite a few differences visible. In most cases the shutter parts are thicker or bigger. The working camera has a serial number that is lower (though the plate on the bottom can easily be changed). So, I think I learned two things. 1) Just because my well-cared-for camera failed, not all SL35E cameras are going to fail. 2) They earlier ones have a better shutter. So, I'm going to go out on a limb here and suggest that the older SL35E cameras with the slotted screws on the cover are better. I know there are a number of APUG users that have these cameras in order to use the fantastic Zeiss lenses. Any comments or other observations from other users?? BTW: I have 4 of the SL3000 series cameras, but lets keep this thread as an SL35E thread.
