I just got a Canon 7D and put the 40D to rest as a back up body. My first impression of the camera is that it’s worth every dime. It truly is an improvement over the 40D, needless to say I think it was worth waiting for it as supposed of going with the 50D when it first came out.
One aspect the I really like about the new body is that I can use the flash detached from the body allowing me a lot of freedom. I have not tried it outdoor jet but indoor is doing a pretty good job so far. The other thing that is a big leap forward is the focusing system, it is faster and more accurate so far and it has a lot more choices (which I’m learning still) and although it has tons of extra features those 2 are the ones that caught my attention the most so far.
This few pictures I took are with the wireless flash function. @ canon 580 EX as main and fill one to the left and one to the right and a Canon 430EXII on the back top left all worked just fine.
The last picture of my daughter was done with available light at a higher ISO Canon 7D and Canon EF 24-70 2.8L
