Originally posted by k100d to add to this discussion, i had an MX which was serviced by Eric as well and the shutter speed dial was very stiff
Mine has only just come back from a CLA, and I was using it during my lunch-break, today. Whatever the shutter speed dial was, it was not enough for me to notice anything.
However, after taking time to make some really well-thought out shots, I did notice that the rewind lever was not turning in step with my film advance lever. After some checking, I felt sure I had not anchored the film leader adequately and it must have slipped out of the take up spool: sure enough, on opening the back, the leader was out of the take-up spool and all my "artistic endeavours" had been wasted.
Never mind. Fixed up the leader and tried to replicate the shots, but the mood was somewhat diluted
I'll check out the shutter speed dial tonight.
