Hey Everyone,

I just got my 5D and am kind of in awe of it!

While shooting weddings do any of you use predictive AF? You have to set up the camera to do this in Custom Function 17 right? It doesn't do this by default, correct?

What are the advantages or disadvantages to setting it up this way for weddings and portraits. It seems like you would ALWAYS want the AF to use all 6 of those little points (in the spot meter circle) to try and focus on a moving subject... Am I right about this? A reference is p.76 in the manual as well as p. 160

Please HELP!!!

Thanks so much,
Katie

I think spot focusing is much better. The only time I use full auto of any kind is when I am not looking through the viewfinder. I know this isn't exactly what you asked, but CONTROL is what you are looking for and the environments of weddings change so quickly, it seems the added control of spot focusing makes a difference for me.

CF17 only activates 6 invisible focusing points which help to track the focus if the subject moves away from the central focusing point. They only work with 2.8 lens if I'm not mistaken. I have them activated in CF17 and activate all focusing points only if I track moving subjects in some cases. In all other cases - selective focusing.
