I purchased the camera repair guide of my OM 1 camera. I am fascinated how these mechanical cameras are designed but can't understand it since I have not the right technical background. I saw some books on ebay on camera repair but they didn't look interesting. I saw an American website where you can learn every aspect of repair with 12 dvd or more at a total price of 3300$ (also digital camera covered). This is too much for an amateur. Any alternative ? I am located in Belgium.
