I realize that most people do not shoot sports, but shooting thousands upon thousands of photos per event is pretty common when the goal is individual print sales by fans, family, and the athletes. 10k shots in 14 hours is extremely easy to do. I have shot 5k at an 8 hour event and that was not difficult to do at all. My 7d's batteries (I have two in the grip) can last for thousands and thousands of shots each. I'm not sure why somebody said they could only shoot 800 each?? Also, when shooting for print sales, often times a smaller sized jpeg is used to save space on cards, and for faster transfer rates to websites. I really don't understand everybody's disbelieving attitude here... And I really don't know any other way of relaying that 10k in 14 hours is common for a print sales sports photographer.
