I'm having a bit of a problem every now and then with my EOS 3. When shooting the aperture will show 00 and I will have to remove the lens and remount it to continue. The rest of the controls all work fine, it is just the aperture that shows 00 and the shutter won't release until I remount the lens.
Now I thought this might be a lens related issue (Tamron 28-75) but there is no such problem with a Rebel 2000 body I also have. I have another cheap Canon zoom that I could use but I don't want to burn film for that as the issue is not very frequent. It happened maybe 5-6 times over 10 rolls.
I also get the impression it is only happening when film is loaded as I fired off a hundred or so frames with no film and there were no issues.
Has anyone had any such issues? I thought it might be a battery problem but I replaced the battery with a new one and made sure all contacts in the chamber and lens mount are clean, yet it doesn't seem to solve the problem.
Anyone else with such problems? Not a big issue, I can get another body for £70-100, but it is annoying.
