I have a 500CM body that is starting to malfunction - the mirror is hanging after an exposure - been in service for a while and needs a CLA likely. Rather than google and pick at random, I was hoping for a referral - like - "I used this person and they were great" ... or something like that. Any recommendations???? Anyway - this gives me a chance to use my HEAVY SL66 that has just been CLA'd by a guy who won't touch the Sweedish bricks. Rats! Should be fun - it is a truely great camera.
