John, was your focus point on the rear two horses? If so, that Sigma looks really good. I was reviewing your focus zone at f4. Now I don't know for certain 'cause I cannot see how much the zone stretches behind the two horses, but if the zone was moved backwards(negative movement) by -1 or -2, you would have gotten the lead horse in better focus also. Of cause, I don't know if this was your intention or not.
I know that you made an adjustment at the track. Check this over
Zee, I do pan at lower shutter for more blur. Just getting acquainted to the gear right now. Thanks
scyfree, the focus with the D3 is a big winner. Still adjusting the AF fine tune in camera for my lenses. With the D3, accurate focus is a MUST. The images need a real fine sharpening, more so than the D300. W/O spot on accurate focus, all the sharpening in the world will not get a fine image.
This image is a bit OOF. However, I bought a remarkable sharpening plug-in..only $9, which appears to actually be covering up the OOF error a bit.
I feel that I am almost there with the 80-200. Just a bit more experimenting to go.
