85 1.2 II AF Question

[Daniel Browning]

So now to the question would a camera body that is deamed to have a faster AF system allow the 85 1.2 to focus on the subject quicker?

I don't know. My best guess is that the slowness is an issue of the 85mm f/1.2 lens itself in this case. Another issue aside from focus speed is accuracy. I would guess that a different body (e.g. 1D4) would be more accurate -- especially if using more than just the center point.

My intuition says the same as Daniel. I have that lens, and the USM driving the front element just feels fairly sluggish-- which is probably intentional, allowing for extremely fine adjustments. That's not going to change much. But if the camera is telling you you're focused and the shots aren't as sharp as you like, a new body might suit your needs.
