I was looking at the following options for C.Fn III: Auto focus/Drive (AI Servo 1st/2nd img priority)
0: AF Priority / Tracking Priority
1: AF Priority / Drive Speed Priority
2: Release / Drive Speed Priority
As a sports shooter, I selected option "0". When would I - or anybody else - use options "1" or "2" Sure, my camera slows its frame rate down a bit when tracking a difficult subject, but to me, AF should be the highest priority all the time (what good is guaranteed 10 fps with OOF images)?
Hi,
I shoot wildlife and use to use 0, but found it too slow and at times it wouldn't take the photo even when the bird looked to be in focus. I was missing good shots. So I switched it to 1 a while back and couldn't be happier
Interesting point Anthony. I just shot a swim meet last night and had that same issue, especially with the two diving sections (the fps rate felt like it was around 6). I'll try option "1" tonight with volleyball
Using the fast slot (SD) set to "1" should be fine. The logic is if the camera didn't shoot, the moment is lost forever. At least if it does shoot it might be good. I lean towards "1" since the only reason I'm pulling the trigger is I believe it is tracking. Otherwise I stop and re-establish.
The SD slot supports 50% faster write speeds which makes a huge difference. The CF slot only supports 9MB/s write. Use an Extreme 30MB/s SD and you get 15MB/s write speeds.

Andrew - where did you learn about this? So all these new 600X and higher CF cards are useless for the 1D Mark III? What is the max speed for SD?
*I almost bought some new CF cards, but now I'll wait until I am properly informed
Alas the only real weakness of the 1D III IMO is CF card write speed. I tended to use SD card as I did on my 1D II as it seemed to take ages to clear buffer after a long burst. 1D III cannot take advantage of UDMA cards, but they will allow faster downloads on card reader at least.
