turbotoes said:I went from a 40D to a 7D a couple of years ago, and found initially that my keeper rate went way down..... However the ones I kept were far better in terms of detail (to my mind IQ) than I could have obtained with the 40D. It certainly took me a while to get to terms with the 7D but when I did I was more than happy with the switch.
Think in in this boat.... I find the awb leave everythink blue.....
