Demolition

I have replaced my Canon EF 35-105mm lens; the first one was in bad shape from the moment I took possession but it cost me nothing and educated me over what a fine optic this is. The replacement has light scratches on the front element but for all practical purposes they don't impair performance. Canon made three lenses in the 35-105mm configuration. The one to seek out is the first, an f/3.5-4.5 formula with a trombone action. The others bottom out at f/5.6 which is not much of a light gatherer. I use mine on a Canon EOS 30D which is ancient and where 35-105mm translates as 56-168mm. It would not suit everybody.
