Was wondering why one would use AF-S, when AF-C focuses continually, addressing slight variations in mvt that AF-S doesn't, so why use AF-S, just leave it on AF-C, I now there are other considerations like speed etc that would affect which AF to use, but speaking purely on focus, surely t here's nothing wrong with just leaving AF on AF-C? or am I missing something(s)?

AF-S can help you set up a focus trap and avoid hunting in some situation (ie AF-S on the ground/ara where you expect your subject to enter, lock the focus and wait for it). AF-C will cause hunting, and especially with a slower focusing lens may totally miss the shot.

Also AF-S will allow the focus assist illuminator to come on in poor lighting, it may make a big difference over AF-C.

At least that is just about the only time ever I use AF-S.
