Motorsport af point setting

[baz83]

Which is a better setting for the af points on a 550d for motorsport?

To have it set to single af point in centre or to have it set to them all on auto?

I know to have it set to servo focus.

Thanks for looking

center point only. having all points set runs the risk of getting background in focus etc.

Thanks for that Neil, thats what I have been doing.Just checking its the best way.

if youre just out there to catch crashes, then might as well use auto.

but otherwise chose your focus point (not necessarily centre)

sorry yes, i meant single not center above. depending on the framing of the shot.

I thought you were best using centre because it is "quicker" or something?

 

[neil_g]

depends on the body and af system. on some bodies center is fastest. but you dont "have" to use the center.

Thanks for the advice!

I used centre with assist when I went to Silverstone, seemed to work OK.

select a focus point, but not necessarily the one in the middle.

Auto is likely to pick up on something you don't want.

centre may or may not be the fastest, but its a bit bloody boring having all your photos focused on the same point

i assumed thats what you meant
