I won't buy anything that says Sony on it, but it really doesn't have anything to do with their cameras. Burned bad on a TV. That said, I have all Canon. Why. When I bought my XT I got a good deal on it. If I had gotten a better deal on Nikon or even Pentax that's what I'd have. I have always loved Olynpus optics but the smaller sensor turned me off at the time and I got a better deal on Canon.

But whatever equpment I have, the quality of my photos is up to me. My eye and my finger on the button. So, a long way around agreement with the premise of the OP.
