Loc: Barrie, Ont,
I've heard a lot of people say that once they've trained themselves to use back focusing, going back to the half depressed shutter button feels archaic.

Is there a reason why I'd choose to back focus, instead of using metering + focus with the shutter button?

I realize it depends on the type of pics you take, but I'm just trying to figure out under what circumstances I might improve my keep rate compared to what I'm doing now.

It has its place, but I use the shutter button. If you're doing something that doesn't require refocus for every shot it's pretty handy.

ah...i like to use it in times like taking multiple shots of people (for a variety of expressions), w/o having to recompose every shot. but it's not second nature pushing that button b/c i don't use it that often.

Do you mean focusing using the LCD screen? I've always known back-focusing as when the lens is off at a certain focal length or when the focal plane is knocked off when while zooming.

I was using your old XS last night for shits and giggles and it's not too bad with custom white balance (and a very fast lens, lol).

No, using the AF-On button (At least on the 60D) on the back of the camera instead of a half press of the shutter.

Ohhhh. Yeah, the only time I ever use that is on 5D2 when I have to focus using live view. Just use the shutter since the T2i I started with featured focus lock on shutter where I think the T1i was different.

99.99% of the time I use shutter release to focus except astrophotography or anything using 300mm end of 70-300mm with no full time focus.

Back-button focusing is the most popular way to shoot sports or anything in motion (ie: birds and animals). I use it all the time.

I use it, when I try to use a camera with shutter release triggered focusing, it does feel weird, hehe. I've got the body set for continuous focus, so as long as I hold that button down it's focusing. When I let go, focus is locked whether I press the shutter halfway or all the way or whatever. I tried it as a test for a weekend and totally fell for it. Can't go back now.
