Over past few years, I have grudingly parted with a few Canon A-1s. The reason, at least with regard to the last two, was that the shutter release button required quite a bit of pressure--so much that I suspected that camera shake could possibly be induced. I wonder, though, that since Canon shutters tend to require more vigilance in regard to lubrication, whether the awkward feeling I kept getting with the release may perhaps have been a problem with a sticky shutter. Overall, it simply did not feel right when releasing the shutter, and this is in comparison to the numerous other cameras I have used. I welcome any commentary on this matter, as I would very much like to have an A-1 body in my arsenal, but I do not want to be disappointed again. I have a Canon P Adapter (M42) collecting dust.
