Several years ago, my Canon A-1 was stolen. I recently located my old FD 35-105mm 3.5 lens and decided to purchase a used Canon A-1 camera on eBay so that I could try it out. It has been a while since I used this equipment (I liked the camera a lot when I owned it), but I have noticed something that seems odd with the lens maximum aperture and thought that someone could help me to confirm the problem. The used camera I purchased came with a 50mm 1.8 lens. The maximum aperture sensed by the camera seems to work fine. When I try to set an aperture of 1.4, the camera still reads 1.8 (works as the manual says). However, when I attach the 35-105 3.5 lens, the camera thinks that the maximum aperture is 2.0 (this seems contrary to the expected operation in the manual). I don't recall seeing things work this way on my original camera, and my lens hasn't been used since my original camera was stolen. It seems that there is some type of adjustment problem with the max aperture linkage pin. I don't really understand how the problem can appear with one lens and not the other. Could the problem be with the 35-105 lens? The used camera I purchased was serviced by a camera technician prior to sale and is still under a 30 day warranty. If the issue can be isolated to the camera, I might have a chance of arranging a repair or refund. Would certainly appreciate any advice.
