Auto focusing, re-compose, re-meter...

Hey all...

So I was playing around the other day with shallow DOF's and was wondering what you guys do when you want to focus on one area but to meter in (AV or TV mode) another.

Currently, I'm focusing on the subject, switching off auto focus, re-composing, check focus (manually), auto exposure (based on TV/AV option) then take pic.

Is this how you guys do it?

Does the 400D have the Custom Function to move AF to the * button?

If so that's the easiest way of separating metering and focussing.

Ohh, so essentially the shutter would only do the auto metering.

This would also mean for every shot that I'd need to...

autofocus(*) -> meter(half press) -> take pic.

That's ok though, in fact would actually be handy to have them separate.. Let me check my manual...

Just go to custom function 4, and select option 3. Took me a minute to figure out which one it was, because there are four, not three, options in the menu, so 1/3 didn't make any sense. Good to know.

Apparently you can do this on the 400D... At work atm, so will test later...

Press and hold the spotmeter button (Button by my right index finger), press and hold the AE lock button (Button by my right middle finger) and finally press the AF lock button (At the end of the lens)

I don't think my lens/camera is good enough to have those buttons? I'm pretty sure that my lenses only have AF/MF and if applicable macro ON/OFF
