Well, it isnt new....but I just bought it off ebay. I got a Pentax MX with a 50mm 1.4 lens and the only imperfections are a little ding on the pentaprism and......the self timer doesnt work. I pulled it back and could hear the clicking and let the shutter go and it didnt time down. Pulled it back a bit further with same result. Is there anything I can do myself to try to fix this? If that isnt recommended then what would be a recommended shop to send it to? I dont mind having it fixed....i dont hold it against the ebay seller, he listed the auction fairly generally and if it was important I should have asked.
