Well, I've probably put 3,000 cycles on her already. Its REAL easy to push through sequence shots with this thing firing on high speed. LOL I couldnt be more impressed with the camera itself. I purchased two lenses - the 18-135mm and the 70-300 kit style (4-5.6)stuff because its all I could swing right now. I'll rent for events. I'd have to say that I am not so impressed with the 18-135 overall, and have not shot much with the 70-300 just yet. I gave up a little bit of lens power when I sold my Nikon stuff, but the camera is worlds above.
My only complaint so far is knowing I need to calm down on the trigger when shooting some of these events so I dont have so many shots to weed through. QUALITY over splattering crap on a wall is going to have to be my focus.
I plan on shooting with the 70-200 2.8L at a moto event on December 1st. I'll get to see her full potential then and report back.
