Selling used Canon 17-40L lens. Only had it for about 5 months. Bought it brand new in the box. Still in excellent condition. Selling because I am upgrading my body to a 5D Mark II and am getting the 24-105L for it instead. This is a sweet little lens for wide angle shots. I love it, but won't need it for my full frame camera. Very nice for bodies with a crop sensor.
