-Official- 1D MK III AF Thread.

...On my 5D using 3fps I had difficulty in getting this shot as you do not know when to shoot.

I'll have to confess, I used to kind of look down my nose at "spray & pray-ers" who rattle off 10 to 20 frames to get the right shot. There was a real sense of satisfaction to snapping my 5D at the perfect moment to get the shot I wanted. However as often as I got a good shot, I didn't get the shot I wanted. That's almost a thing of the past now. I love the 10 fps with this MkIII but even still, I use it judiciously. I don't want to wade through 50 shots to find the one I want.

Well here is another shot from my weekends escape for the past 2 months without much satisfaction as the bikes were too fast for me or I was too slow in choosing that moment with 3 fps on my 5D.

Tried this out the weekend when I took the 1D on my first trial run and hey presto, panning with 10fps is made easy even on approaching angles as in this shot where I stood at an angle where the subject approaches at about 10 to 11 o'clock with AI servo on with speed at 1/80 (will try 1/30 the next time).

Good job Peter.

I'm going to an air show tomorrow, I was thinking that the AF's default settings should be ok or do you guys recommend different settings for aircraft?

James,

How was your airshow?

You are right. The speed was 1/80. Have corrected the text in the original text. Should have referred to the exif.

It was cancelled due to bad weather

I guess you were planning an trip to the RIAT then. Saw it on the BBC last friday. Terrible weather indeed

Yeah

Question :

When firing out 10fps do you keep it on Servo, or Single Shot focus ??

Depends on what you're shooting, but I would assume 99% of the time AI-Servo.

Ta.
HAveing never tried it i didnt knowi if it was a case of focusing once and waiting for the shot to be in focus sometime in the next secind or so, or whether the camera has enough time to adjust focus between every shot.

Well, yes, that's what AI-Servo is supposed to do. If you are on one-shot, the focus would stay fixed no matter how many shots it took.

Yep, I agree. Odds are if you have a reason to shoot something at that frame rate, it's probably because it's moving pretty quickly, so AI-Servo would be the mode to use.

What a let down! Was waiting to see those fantastic flying machines you captured in mid air. Don't worry there will be another day.
