Not sure on some of those but mostly not supported. DPP 3 is still better than ACR from where I sit. It does not look as if they will add the older bodies to DPP 4…. I have nothing against bodies like the 50D and 40D. I do not know the others :).

Hi Barry, I say it because that is what I have been doing :). I suspect that you meant to ask “Why have you been doing it?”

There are several reasons why I have been using shutter button AF more and more:

1- With four triggers fingers and a bum left thumb and wrist in addition, I find that having one less thing to do with my right thumb makes things easier overall. As proponents or shutter button AF (including Denise Ippolito) have been saying for years, it is easier to do one thing than to do two.

2-When hand holding it is always best to be in AI Servo AF. With the wider AF point array on the 7D II it is easier to get an AF point on the bird’s eye or face. This enables one to get away from rear focus and re-compose, a big plus when hand holding.

3-I have enjoyed the convenience.

4-By setting the AF-On button to AF off you can effectively have One-Shot and re-compose while using shutter button AF.

Please note that noting is set in stone and that we need to be learning and adapting every day.
