I've had the camera for a week. It's the first SLR I've used in 6 years, and back then it was in high school and the teacher took care of most of the settings.
Anyway, I just got the camera, an EF 70-200mm f/4L and took it to a hockey game last night (local team) and started shooting... in MANUAL mode.
It was my first shoot and in about 60 shots (though I took many more and deleted most of the REALLY bad ones on site between periods) I pulled a dozen or so that I was really pleased with. Now, by no means were they professional level, but pretty close. I was more than excited that (after reading the manual) I had such great photos in just one sitting and I look forward to getting bettter with each shoot. I also love that I am able to read off the camera settings at the time the picture was taken so that I can learn from my mistakes in the process, something I couldn't do if I was shooting film.
