So two years ago i purchased from KEH a 35-350mm EOS L lens. The bease is very heavy and cost me a grand. It was listed in Ex+ condition and was a fine lens. Today I lost it. As i was shooting some bugs and flowers while walking the mutlies, the 1Ds and the lens fell onto the ground and promptly bent the tube. Now this lens is an older lens and no longer supported by Canon. Looking at it, and finding that most of the lens was no operating, I took it home and decided to take it apart to see the damage. Not to salvage, but to see what broke. Upon taking it apart I discovered over-tightened screws, and screw heads that were stripped and covered with black sharpie ink. The deeper into the lens I went I found all kinds of little tidbits including the plastic electrical coating heavily worn and a few other items. Realizing this thing was gone the last resort was to simply toss the mess away. A loss of a good lens. I don't blame the KEH folks one bit. Unfortunately it looks like someone had taken this thing apart once before (there was also a missing screw) and I found evidence of the Canon white touch-up paint in specific spots. So dont think the the KEH folks are to blame. They are not. It looks like someone did a once over on the lens before selling it to them and just happened to get it. Cest la vie.
