Last Friday I went out with my Olympus OM1, some rolls of cheap colour film (Fujicolor 200, £1.50 a roll from Firstcall), and 28, 50 and 135mm lenses.
First weird problem I had was sometimes the mirror didn't go back down after taking a shot until I wound on. This happened a few times if I wound on immediately after taking a shot, but if I didn't wind on until just before taking the shot, it never happened. Could be just as I'd not used it for a while and something was a bit sticky?
Then in the last photos before I called it a day, I got what looks like a light leak. In inspection, the back seals look pretty gone.
While the light seals are probably something I can sort myself, that sticky mirror might suggest a CLA is required.
Any one had an Olympus serviced in the UK and can recommend anywhere?
