Canon 50-200mm f3.5-5.6L $400 Date Code UD0104 push-pull zoom. Includes both caps (the rear cap is an after-market cap), but no hood. This is a rather rare lens, and makes for a great lightweight travel kit when combined with a 17-40 f4L. The glass is in perfect condition, as well as the lens barrel. No nicks, rubs or anything else. There are a few (very tiny) dust specks in the lens, but these have absolutely no impact on image quality.
