I'm going to be shooting a CrossFit fund-raising event this weekend and plan to rent a 5D3 for it. Everything I've read says you need some time to get up to speed with the camera, and I have exactly 1 evening, so I'm hoping maybe some of you experienced with the camera can help identify what settings I most need to get familiar with (or maybe even what they likely should be.)
FWIW, my experience is with an Xti, a 40D and a 7D.
In short this event will be indoor sports--crappy lighting, moving athletes. For most of the events, the athletes will be moving in one spot, for example doing deadlifts or hand-stand push-ups. There is a sandbag sprint, so that will be a bit different with the athletes moving linearly. The other thing I'll be doing is spending very little time on one athlete/focal length. Some of the events are as short as under four minutes, in which I'll have to capture 8 sets of 2 athletes each doing 2 movements. I've done these events before with the above mentioned bodies, so I know what to expect as a whole; just looking for help to maximize my results with the 5D3 in this setting. (Although now that I've said that, I'll retract it and say that I'm open to any and all suggestions as there's always stuff to learn--I certainly don't know everything!)
Thanks a bunch!
