Can somebody tell me what is the best options to choose when taken action photos. What selection should I use in metering mode and what selection should I use in AF area. Thank you in advance for your response.

If the action is predominantly coming from one side, setting the AF points to that side will help in composition (photos look balanced when the subject is looking/moving INTO the frame, rather than moving out the other side). If the action moving everywhere, but in a small region, the central focus point may be best. Moving everywhere, but scattered/diffuse region, just leave all points active. {This is where the Canon 7D excels -- one can pick any of its focus points, and then expand the area to include surrounding points}.

Set the camera to continuous focus mode (predictive/servo/AI) -- this mode will NOT lock the focus (and also will NOT give you an in-focus indication). Hold the shutter button halfway down and TRACK the subject -- the camera will attempt to keep focused on the subject -- press the shutter completely only when you anticipate "the moment". Do NOT release the half-press or you'll have to start over letting the camera seek for initial focus.

If you have the ability to specify that the metering area is tied to the focus point, that may be most useful. If you are using the central focus point, a central-spot meter (~10-20% of the frame) or spot (3-7%) may be useful. Otherwise I'd leave it in evaluative/matrix mode.

Thanks Dennis for the info.

Which camera do you have?

Which metering mode can be influenced by what sport and what the lighting situation is. Shooting football at night at a well lit outdoor field is different from ice hockey is different from MMA with the cage lit and the audience dark.

The iidea of offsetting the focusing point takes considerable skill to avoid not placing the subject in the centre of frame and improving the composition by cropping in PP. I wonder if it is an instinctive reaction? :-)

What kind of action under what kind of lighting are you shooting with the Sony a33? Are you using variable or constant aperture lenses? All will affect the best way to approach focusing and metering.
