Very slow focusing
3 months ago

I was trying my D3s yesterday and noticed that the focus was very slow with used with 70-300mm VR.

Is this normal for this lens to be very noticeable ? would other lenses focus fast such as 2.8?

The reason I am asking is that I tries my friend's Canon 1D mark IV with 70-200mm f2.8 and it was very smooth and fast
