I just took delivery of my 7D 2 days ago. I used to shoot with a 50D. After several years using the 50D, the transition was not to harsh. I took a bunch of photos yesterday at City Park, in New Orleans. I used a Tamron 18-27mm lens. All the photos were very good. I just needed to get the "feel" of the 7D. Now, I'm going to experiment with some video, bracketing, and some high speed burst shot. Note, the 7D is heavier than the 50D, but the 7D is more ergo fit to the hand. I'll be snapping on a long lens today for some test shots in the backyard, hopefully there will be something to shoot. The weather here in New Orleans, has been really hot, not may animals, or birds moving about.
