Default C.FnIV: Shutter button/AF-ON button

Which option do you use and why? Are there circumstances/situations when you change this option to a different option?

I think its C.Fn 4 -2 for me ...

That sounds like it, but on mine its the * button for AF and the shutter release just controls my shutter/meter/IS

I do it because i like having AF and shutter seperate

Default Re: C.FnIV: Shutter button/AF-ON button

I use the default (0) setting for ordinary shooting with One Shot AF but change to separate focus (2) when using Servo AF for action shooting.
I usually also switch the AF-ON/* buttons, since there for some incredibly stupid reason is no AF-ON button on the BG-E2N grip.

#2 for me. I shoot action interspersed with static subjects and having the AF on the back button lets me keep my eye to the viewfinder instead of repeatedly flicking between one shot and AI Servo. For most cases the metering for #2 is what I want. If really need to lock the metering for a recompose I just switch to manual exposure.

2 - for when I'm panning or tracking action e.g. birds in flight
3 - for general purpose.
