Hello everyone. I'm shooting the Chicago marathon next Sunday and wanted to get some pointers/ideas on camera settings for that (I have no experience shooting moving objects with the D30 yet). A few things that I'm curious about:
1. How well does AI Servo work? I think I recall a post from Pekka complaining about AI Servo always "lagging" somewhat.
The biggest problem there is that there are only 3 af points and the center point is most sensitive (horizontal & vertical contrast detection, side points are only horiz.)
I haven't shot any sports yet, only some moving subjects, and if you want to compose to other than middle area of a frame you have a couple of choices: find a focus spot from the ground level and take the shot when subject is on that spot. That could work well on marathon where athletes don't jump like crazy. Or, shoot with AI but with smaller aperture which lets you hold the focus and even recompose if you're fast.
In either AI servo or single focus mode I like to keep the focus on * button (Cf. 2-3). In AI servo it works so that the camera does AI focus while the * is pressed and when you release it the focus stays still. When in standard mode you can just press it once and that lock the focus point. If you keep tapping is gently you can sort of emulate AI servo.
Remember that if you move the camera (shake, pan, tilt) and the subject is moving you have to have at least 1/250 or 1/350 speed to stop movement and get really sharp shots, often even more. The closer the subject the faster the shutter has to be.
2. I will be close enough to the action to shoot with a 28-70 f/2.8L with monopod. What's the maximum ISO setting that are likely to produce results without unacceptable noise (for prints up to 8x10)?
ISO 400 is quite ok, ISO 800 can be great IF you expose so that you can get a bright image. I usually overexpose 3/4 stops in ISO 800 i.e. loose some minor highlights but gain low apparent noise level. See some ISO 800 shots in my gallery.
3. One major issue is whether to shoot in RAW mode or "sport" mode (Large Jpeg). Anyone with experience shooting "slow" sport in both modes to help me out?
If you shoot RAW in continuous mode and keep the shutter button pressed half way you can shoot a new one as soon as there is room for it in buffer. If you raise your finger fully you'll have to wait for writing of all images in buffer. This needs a little practicing but actually is very useful.
