New to the 5D3 after years and years of using a 50D with nine focus points. Finding it a bit overwhelming to start with.
Firstly I usually use one point AF, but there are two options 1 spot AF and 1pt AF. I'm reading that spot is for more accuracy. Is one faster than the other, I can't see why you wouldn't choose spot all the time?
Secondly when I shoot football using AI servo would you change that to Zone AF or an expanded/surround set up?
Lastly back button AF which I use a lot with my 50D and you go to custom options to set up the AF-ON. Looking at the custom settings am I right in that the Mk3 AF-ON is already set up for back button AF I just need to turn off AF start on the shutter in custom controls and switch that to metering only?
Sorry for the questions 3 year late but this AF is a hell of an upgrade on what I had and the booklet isn't all that great.
