Originally posted by twitch Do others move focus points around during a burst? Is this then a disadvantage of back button focus?
Not during the burst, but just before the runners get close enough, I change the focus point to whichever of the 4 corners will put the athlete I'm tracking in the right place in the frame. For that matter I don't shoot an actual burst anyway - I shoot about 1-3 photos (usually 1 or 2) of a runner that I
think I got well framed with the runner in focus. Because my photos normally post immediately to the web, I can't afford to take more anyway, and I don't want to deal with more either. But bursting may be a better idea for most other shooters.
Typically I keep the same focus point for the next 10 or more runners I shoot, but then I may change for a different composition. So usually I'm going for the traditional shot of a single runner running in to the empty space of the frame. But sometimes I see something else I like, such as a runner leading a group, and I may position him heading out of the frame with the others following. This gives the illusion of him "winning," even though he may only be leading a small pack that's really in 50th place or something.
Here are my shots from this weekend, at the world's largest cross country meet. I was also producing live streaming video from 2 remote locations on the course, so I was mostly concentrating on that. I've noticed this causes the quality of my photos to suffer, since there are many factors to consider when composing a sports photo. Nevertheless, I got photos from the key races, plus a few others. This time I threw out up to 20% of All Photos, and if you look at that gallery perhaps a few more should go. But it's still achievable to have the majority of your photos come out usable.
