    Sean, set the a700 to DMF. may not work very well for fast moving subjects but at least it will pick the AF and then you fine tune in MF.

    well to tell you the truth, i have not read the manual for the a700 yet. have the pdf downloaded but yet to read it.

    however i think i read about it on Dyxum or DPR forums on a bird thread.
    i've used it several times and it has worked out well on the 28-135mm. maybe it is cause that lens is rear focusing so it is pretty easy to MF on it on shutter is half-depressed.
    doubt it would be very useful on the beercan unless i have a tripod.

    The A700 has DMF? I think I recall that being not available in the A300.

    yep it does. not sure it works in AF-C but it does in AF-A and when shutter is half-depressed, it changes to AF-S and MF.
    it would probably work a hell of alot better on live view and a tripod.

    LV though doesn't give good enough a picture to determine focus accuracy.

    Where I find DMF excels is taking an image using "spot focus" and then, as you achieve focus lock with the AF ... you can then adjust the lens' focus ring manually to get something in focus that wasn't quite centered under the focus spot. It does help to have a manual focusing screen in the camera, too.

    In AF-C or AF-S ... the focus ring on the lens is locked to the camera control, throughout the shot. You cannot adjust it, unless you toggle the AF/MF switch. It just autofocuses as best it can.

    Something I've been using recently is LOCAL focus. Quite useful in composing certain shots quicker than readjusting composition from SPOT focus. It's a shame the AF points are so centered (more a shame on the A900).

    the problem isnt with the body, the problem is with the AF speed of the lens. (or lack thereof).
