Hello everyone!!!! This is my first post on the website and I am fairly new to photography. My friend is a professional boxer and I am going to take pictures of him boxing this weekend. Now I just got the new Canon 50d and I am still getting use to it. Can any one give me any advice on: 1. Which set up to use?? 2. Which lens?? Out of what I got. 3. Setting on the speed 4.Etc... Please feel free to give me as much advise as possible, I am like a sponge I am taking everything in and I am going to try come up with the best pictures possible. Thanks in advance.
