評價:
very good lens, price reasonable (compare with LB4, LB5, sigma 70-200 HSM f2.8 and Tamron 70-200 f2.8)
The picture quality is sharper then Tamron and sigma, no doubt, I personally tried those lens and LB3 is the sharpest in those 3 lens.
The Auto Focus is very fast when used on D700, faster then using it on D80, I think the focus speed related to the body.
I have been thinking to get either Sigma 70-200 f2.8, Tarmon 70-200 f2.8 and LB3 for a long long long time....each lens have their pro and cons, sigma is good at focus, very fast but soft at f2.8! 
Tarmon is the cheapest and lightest with usable f2.8, 
LB3 have the best picture quality, fast focus when used on D700( D3 or D300)
