    Absolutely. AF-ON is the only method I use ever. No switching between AF-C and AF-S and I control the focus, not the camera. Also seems to get more keepers with moving subjects.

    Doesn't have an AF-ON button, but you can program the AF-L/AE-L button to function the same as the AF-ON button would on a higher end Nikon body.

    Highly situation dependant as is the choice between AF-C and AF-S shooting modes. I find AF-On to be most useful in situations where there is a high chance of not finding focus for macro shots or night shots where you may want to focus once and shoot multiple frames.

    I don't know about Canon but my Nikon has an exposure comp button about a half an inch from the shutter button and a thumb wheel to make it do whatever you want. :)

    I've been doing this for years. It now freaks me out when I pick up a camera that uses the shutter release button to focus.

    CF4 all the way!

    Mostly the AF-On but as Garbs said it is really dependent on the subject. Which is true with any settings you will use on your camera or, should.

    Why would you use the back button?
    I prefer the half-press shutter, its quicker to use and I dont use exposure lock much
