I’m not sure what the difference between spot focus and selecting the center focus spot. But that’s basically what I try to do, and I was still having the problem. > I don't use any of the multiple focus point or Select modes unless I'm > shooting sports with AF-C. With dancing (or martial arts) I’m basically shooting sports, though I’ve traditionally had poor luck with AF-C in low light conditions. I usually need to pre-focus and lock focus (using the af button). Unfortunately, it seems to then lock focus on something in the background. > If you're shooting a lot of movement you might try using one of the Expanded > Area modes, but they only work using AF-C I may try AF-C again, I don’t remember how long it has been since the experiment where it didn’t work, things could be fixed by now. > > -p > > > On 12/2/2019 5:40 PM, Larry Colen wrote: >> About a week ago we went to the Dickens Christmas Fair at the Cow Palace >> (Daly City, very close to Brisbane).
