I spent the weekend shooting with the 7D. There is definitely a learning curve moving from the Canon 40D to the Canon 7D. Those 19 AF points can be frustrating. They seem to pick the object closest to the camera to focus on. I had much better luck focusing with the Zone AF or even the Single AF. And yes, the above shot was taken at ISO 3200 with the standard NR setting in the camera. I just used Photoshop to level off the horizon.
More 7D stuff coming this week.
