17-40 L and 7D seems to work

Nice shot! I just sold my 15-85mm and picked up the 17-40mm this week for use on my 7D. I had what I felt was a very good copy of the 15-85mm but I know full frame is in my future so I decided to make the switch now. After several days of testing it out I couldn't be happier! Sharp as a tack and the contrast and colors are great. Don't miss the extra range as I have it covered with other lenses. Not to mention the 17-40mm just feels so good to use. Well balanced, the zoom feels good and just a pleasure to use!
