A few years ago I test drove a 2009 Chrysler Sebring for a car review I was writing for The Truth About Cars. The salesman who accompanied me kept comparing this crap Chrysler with the excellent Acura TSX. The lie was so outlandish that all I could do was laugh inside. Anyway...

I own the discontinued Canon EF 100-300mm f/4.5-5.6 USM, which is built a little better than Canon's various 75-300mm zooms but is optically pretty similar. It is a fine lens for well lighted subjects and if you keep it zoomed between 100mm and about 250mm. After about 250mm, the sharpness drops off quite dramatically. Within those constraints it has been a pretty good lens and I've taken many outstanding images with it, although I don't use it much anymore because I now have better glass.
