Just bought a canon model 7. Did some test shots and noted that at 1/1000 no picture came out. At 1/500, half of the photo was black (right side if your looking at the photo). On the other side of shutter speeds, 1 to 1/8 sec does not function. Your suggestions on how to correct this is highly appreciated. Thanks
The camera is in need of a good cleaning and lubricating. You may wish to download a service manual from this site and see if you are confident to do it yourself.
