I'm photographing a friend tomorrow who is a world class Jeet Kune Do martial artist. My only camera is a Sony RX-10 with a 2.8 24-200 zoom. It's not an indoor tournament or exhibition and I'm doing the shoot outdoors. He says JKD is street fighting, so that's where the shots will be taken. There are some good white walls in the town so I was thinking of using these as the backdrop. So... any tips/hints on focussing, exposure, shutter speed etc. I was going to use burst mode as there is no way i can actually capture a moment in a single shot... he's just too damn fast. He want's proper action shots rather than staged poses. But what about focus? What focus mode? Or is it possible to stop the lens down to say 5.6 and just manually focus on a spot... i.e. if I am X feet away just set focus on that distance and fire away. And shutter speed... Am thinking I should try both fast and slow(ish). My concern is that maybe at 1/1000 or so the image might look posed. But with 1/250 it might introduce a bit of motion blur. Anhoo... anyone's experiences most welcome.
