I've been putting off upgrading my current 5D. While I have no interest in giving up my full-frame sensor I've been toying with adding a 7D as a backup.
Why yes Doug, I've had one for a couple of weeks now. I've got less than 100 clicks on it so far but I really like it. The viewfinder is HUGE compared to the 5D.
i had a 7D when it first came out. Although it had all the bells and whistles, the image quality was terrible. I'm using all top notch L lenses, and no matter what, I couldn't get anything great. My rebel was far better for image quality.
I own a 7D. It is a great camera. Very good for sports. Some the 7D is almost or just as the Mark 5. It alll depends on how you use. The interface of a 7D is very similar to the Canon 5D mark II. Both are good cameras.
