I have a Rolleiflex MX-EVS that I recently sent off for a CLA to a well-regarded tech. This is the type that has a separate self-timer mechanism. Although I don't use the self-timer that much I asked him to check it as several times previously it had failed to trip the shutter but I never really tried to pin down the exact behavior prior to shipping it off for the CLA. The tech checked it and said it was ok. Upon receiving the camera back I've discovered the following behavior: 1. If the camera DOES NOT have any film loaded the self timer will wind out and trip the shutter 100% of the time as expected. It is understandable that this would have led the tech to believe the self-timer was operating properly so I'm not blaming him for anything. 2. If the camera DOES have film loaded the self timer will always wind out but virtually never trip the shutter. I have experimented with this at great length and notice that if I continually focus in and out after the timer has wound out it will sometimes(not always) trip the shutter at some random point in the focus movement. It also seem to have a higher probability of tripping the shutter near the end of the roll, say frame 11 or 12 but the instances of such are still quite low. I asked the tech about this behavior and he said he hadn't encountered it before so my questions are if anyone has encountered this behavior and/or if anyone who understands the mechanism could offer an explanation of how having film loaded would interfere w/ the self-timer's ability to trip the shutter. Is this even an issue that might be solved by opening and cleaning the self-timer mechanism or is it something more subtle? I've already put quite a bit of $ into this camera so I guess I'm trying to get an idea of whether it is a good idea to send the camera back to this tech and what might be involved if this is an atypical repair issue.
