Put in 40MPH or even 30MPH and the car would have traveled 58 feet per second or 44 feet per second. So the car traveled about 145 feet or 110 feet in 2.5 seconds whatever MPH you use.
Other than 20 and 21, the shots are all sharp. Pretty similar to what I've gotten with the 5D (except that I'd have about 8 frames instead of 25). It will be interesting to see how well it tracks a smaller target (the "bird-in-flight" shot is what comes to mind).
Hi, Tom..
Yes, my 5D is pretty good for AI SERVO shooting too, but the feel is just so different compared shooting with the 5D and 1D Mark III, the focus is so quick even compared with other 1D bodies.....
I don't shoot birds and sports.. and the 200mm is the longest lens i use, so even the 1D Mark III really has some problems with longer lens and AI SERVO which i might never face at.....So i am satisfied with its perfoemance after returned the first problemed 1D Mark III with err99

Hi,
Very interesting, just noticed that you have two IDs here-----72chevelle454 and kazman442
Got my MK III this morning, did some brief informal AF tests.
One shot appears to be on the spot 100% o the time.
Did some AI Servo testing of a person jogging several times in late evening light, 75deg or so, tracked with nearly every shot sharp. Center point only.
Curiousity question . With a lot of people having AF problems, or "alledged" problems, has anyone really heard anything from the SI photographers & the Pros? We know a lot of them are out there using the MK III, but I really haven't heard too much from them. Hoping that they may post some of their settings soon, like they did for the other Canon cameras

I've posted some of this before...Take it with a grain of salt because it is second hand information. However, it is coming from a colleague who I know well.
My colleague shoots track and field. He is often shooting right besides the top SI T&F shooters. My colleague has a 1D3. Several of the SI guys also have the camera. I've asked him about the AF problems. He insists that he hasn't had the AF problems. He also states that the SI guys are not having any problems with AF. They all love the camera and would not trade it in. The SI guys have being using the prototypes as well as production models. NO PROBLEMS!!!. I asked this question several weeks ago when they were shooting T&F in Portland. I asked my colleague again last week after he shot the US Championships in Indianapolis. Again, the comments from him...NO PROBLEMS. He and the SI guys have shot thousands and thousands of T&F shots. Also, there was a contingency of Chinese shooters with the 1D3. NO PROBLEMS...They insist that it is operator error.
I would think that they would know if there are problems similar to those reported by Galbraith. Moreover, if there are problems, I would think SI would stop using the camera and return to the 1D2.
Now who do you believe?
Jim
PS: SI will be posting their settings recommendations soon for the 1D3.

If the AF of the MkIII is more sensitive, it would follow that it would be more apt to focus on something other than the subject, if the focus point strays off the subject.
True...then is it the camera's fault or the operator's fault when the focus point strays off subject?
If the camera is designed to be very sensitive and very fast in AF, then dumbing down the system seems to be the answer for us mere mortals who can't keep the focus straight.
Still wondering if there is anyone who claims there are no AF issues with their Mk IIIs under Rob G's problem conditions (Bright Sunlight and warm/hot temperatures)?
