them to fix it.

I already send an e-mail to CPS. I talked about it on the phone with Canon and also send them an e-mail. Twice in two weeks. Still no response.

Interesting, the main thing dont give up talking about it, the moment you do, it will never get fixed

UPDATE: I've received the replacement 5D3 and will report back after I've used it a bit to compare to the first body I had trouble with.

Many times I have been at a wedding reception and I get frustrated with very slow focusing issues related to the AF assist beam. I have messed around with turning it on and off and there is a very noticeable difference. For example with my 70-200 as long as I find an area of some contrast it will focus almost instantly even dark situations. As soon as I turn it on it sometimes takes a full second or two to lock focus. I remember my 5D2 having improved focus with the AF assist from the 580exII. Is it a flash issue or a camera issue? I know there are a lot of you who have the same problems. Anyone find any solutions? Most of the time I don't need the AF assist but when it is pitch black and I need it it would be nice if I could focus a little faster. I just don't understand how the AF can be so great in almost all situations except this one area. Of course when I call CPS they claim they have never heard of an issue.

I was wondering how the camera was set up to shoot, was it in one shot mode or AI servo? Ps have you tried using center point only? I am interested in this set up myself but now am a little unsure i want to until the issue is solved.

The AF assist only works with one shot. I usually use the center point if it is really dark because it works a little better. I would still get the 5D3 and a few 600ex-rt flashes if I were you. They work great considering this one issue which is frustrating but you can work around it fairly easily.
