Those who know lenses already know that this is simply the best 100-400 you can buy for your Canon. Used with an APS-C body, it gives the equivalent of almost 600mm max range, but with a full frame camera, it is stunning at 400mm. If you shoot nature, this is a "must have". This lens was cleaned and serviced about a year ago and is in top notch condition. Comes with the original travel case. I am moving on from photography. I also have a complete 70D camera system listed separately. I also have a Canon 70D body with 18-135 lens listed separately.
