I would not be surprised if my 600 isn't delivering what it should. But this is not conclusive right now. I've always sensed the IV was tracking better than anything I know. But between whatever problem I was having with front focusing and was fixed when I sent my IV and 600 in for "adjustments"(have no idea what they actually did),, and micro adjustment inaccuracies,, it's been a struggle. I literally only had two days of shooting over the winter that the camera was giving me anything I could use. This image is one from the first of those two days.
One thing I am seeing that I can tell you for sure to watch for is if you track a subject in that is coming at you, or relatively so, the predictive servo will track ok enough--until that is till the subject slows to land, then the predictive algorithm keeps going, and does not react quick enough to the slow down and you loose the shot. Bumping and servo tracking right at the moment of the touch down or when you actually want your shot is the best I have been able to do.
I do not consider this shot to be as sharp as it should be, but just as of yet don't know what the problem is. I suspect the lens more than the camera for now--or maybe the predictive feature locked on but not perfectly for as you can see it's one of those landing events.
I'll let you know when I know more. Where's the sample of Dougs owl shot, or are you working off the posted jpg?

**EDIT: OK Arash--I see where Doug posted the 100 % crop of the owl further down on the thread. It is definitely sharper--I'll play with dpp and acr sharpening and see what kind of difference that brings to the table.
The other thing--which could be the problem--my shot was taken during snowing conditions 100 feet away. This ALWAYS softens the image. Dougs looks like it was taken in some very sweet late day light--which would give the AF every thing it needs for the best accuracy and give the cleanest contrast and detail. I should post some of the stills I have for all to look see also.
