I've been looking at some other shots with my 24-105 and they look perfectly fine. So, I think it's either the lens or my technique with the longer lens. I may revisit this in more depth in a separate thread; don't want to pollute this photo sample thread with too much off topic discussion.

Thanks for the quick feedback here. I'll update if I draw any solid conclusions.

AI Servo focus --

I've been playing with my Tamron 70-200 and 60D combo and trying my hand at tracking/shooting with AI servo for sports. My results have been mixed at best. And, I'm concerned that the AF motor on the Tamron is a bit slow when tracking moving subjects.

Some examples from a little practice a week or two ago. All shot with center point AI focus at f/3.2. Distance to subject was probably 25-45 feet. All of these were shot RAW and minimally processed in a batch in LR5. The first shot is the full frame as it was taken and the second is a crop of the center of the image . . . not quite 100% crop, but close enough to see a little more detail. I have many examples, but this group is pretty representative. All are from a burst of 5-6 shots as my son runs down the field.

The first shot of the burst is fine, no complaints there. But as he moves and the burst continues, the focus tracking definitely can't keep up.

Shot 1 of a burst sequence (162mm - f/3.2 - 1/3200):

Would love some thoughts from anyone else who has shot this lens using AI servo and whether I've done something wrong, or if the AF motor is just not up to this particular task. I love the lens. Optically, it's fantastic, the VC is awesome, and single shot focus is dead on even at 2.8.

Mine performed great.

Thanks! I am really loving this lens. Great image quality at a fraction of the cost of the Canon version II.

At F4 (and a shorter focal length), you have more give when it comes to DOF. Set your aperture to 5.6, and I bet you'll get similar result :)

Well, if I wanted to shoot at 100mm and f/5.6, I've already got a lens for that. :)

I had a chance to try some more soccer shots last night. At f/4 focus was much better; not as consistent as the 24-105 was, but better. I did get some decent shots at f/3.2 but it might have been only 25% accuracy past f/4. Some evidence of back-focusing in spots as well.

You have to compare them at equal focal length. 200mm at F4.0 is still shallower than 105mm at F4.0 :)

Taking these kind of shots are a bit more challenging when you're also the subject :)
