It seems to me that was a problem with 70-200 VRII. I use my old lens without a problem but when I put my new 70-200 VRII on, I noticed back focus..

I did some autofocus testing with a D3S and 70-200 VR II.

The setting was:

  • Dynamic Focus with 9 points and Auto Lock on OFF

  • VR off

  • set a minimum of 1/3200 sec

I did print scren with View NX to show the Focus point.
The images are dogs running fast in my direction (in 45 degres angle).

I observe backfocus when they are in movement and ok when no movement.
Any suggestion why this problem?
Any potential delay in the autofocus in dynamic mode?

This one is ok...no movement.

Thanks!
