AussieByron,
i guessed that you meant the AF-Mode and yes, it still hunt,
focusing fast and nervos from one object to another, lesser but still too much for me.
It may be that this issue depends on the camera and it's autofocus system, but there
where a lot of complaints about that from persons with different cameras so it seems to me
that it is a lens related issue.
Try to borrow one and you will see what i (and a lot others) mean.
I almost never use a focus light (except on night dives) because i find
that it shy away the animals i would like to take a picture of and
i rarely have focus issues with my "old" 105mm.
Some time ago i got a very good deal on a used 105mm VR and so i borrowed it to do
some tests using a focus light as i was aware of this problem.
Even if the price was more than fine, i don't bought it because of it's "nervous" soul.

P.S. This is my opinion about the 105mm VR and may be based on my experience with the
105mm non VR. Someone else may find the non-VR beeing too slow and apreciate the 105mm VR.
