I was eager to order a couple boxes of TMAX400 120 films and was in the middle of my first roll when the mirror locked up, preventing me from winding the shutter crank. It happened once before when I first got it, but I thought it was just me doing something wrong because I didn't know how to work the camera yet. Somehow I was able to get it to unlock, but not the second time. After a week of researching online, it appears to be a fairly common problem with these vintage cameras, probably due to some springs losing tension or just needed some lubrication.
While I was examining the camera with a flash light, I noticed a few of pinholes on the shutter curtain as well! So, now even my half finished first roll is in jeopardy as well... I'm not sure if I should even get it developed with only 8 exposures. My father-in-law also dropped off a stainless developing canister, so maybe I'd give it a try to develop myself?
Have I gone off the deep end? It sure is fun, though :)
