Seeing the rising prices for cameras these days (either because the amount of working film cameras on the market is declining or because the demand went up) makes me wonder what to do in case one or both of my two main cameras (Canon F-1 and Bronica SQ-A) develop a problem. There also aren't many professional experts in my area who can repair / maintain my gear. It's not only that I don't want to spend tons of money, I'd really like to be able to properly CLA my own gear. That being said, I'm 100% sure that it's quite difficult to simply "do it" on your own. When looking at a service and repair manual for the F-1, I feel rather helpless because, though I may understand where the parts are and have a basic idea what they do, I wouldn't be able to do any adjustments by myself because I lack the knowledge what exactly the shutter of the F-1 does. I have a "feeling" what the 2nd curtain is etc. but I'd really like to learn more. This lengthy intro leads me to my main question: can you recommend camera repair books that cover the many basics of a classic SLR? I've heard good things about Thomas Tomosy's books but I don't know if they actually are what I'm looking for. Any advice is highly appreciated. If you have useful links, I'd appreciate those as well. Cheers!
