    I have recently bought the GX1 and among the AF functions I see it has AF Continuous (AF-C) in the AF menu and AF Tracking the drive mode menu. If I want to take pictures of moving subjects (birds, other animals...) I can't tell which is more appropriate.

    It seems from the manual that AF-C is more for video in other words where the subject is allowed to move around within the frame; and AF-tracking is used where you keep the focus point on the subject and follow it through. Is this a fair assumption? Would you use AF-C for stills?

    Thanks for any advice.

    With AF-C in 1-area mode there will be a single focus point on the screen and the camera will focus on whatever is at the focus point. If your subject moves the camera will focus on whatever was behind the subject (assuming you're still depressing the shutter trigger half-way). You will need to move the camera and keep the single focus point over the subject to maintain focus.

    With AF-C in AF-Tracking mode you will again have a single focus point to aim at your subject. The difference now is that if the subject moved the focus point should also move to keep the subject in focus no matter where it appeared in the frame (again assuming that the shutter trigger is depressed half-way).

    I'd think that AF-C with AF-Tracking would be best, assuming it worked well! My experience with some lenses is that they do not focus very quickly so anything you can do to avoid the auto focus hunting around will be a good thing.
