9 out of 10 points and recommendedAF speed,IQ,VR works wellnone really!
New to forum, I was searching the net for reviews on this lens and found this site,the reviews for the lens made me decide to go ahead and buy it. I've been searching for a lens to take me to 300mm and been torn between a few different lenses the prime 300/F4 ...80-400VR....Sigmas lenses in this range.....wanted the flexibility of zoom (primarily the lens is for sport) so ruled out the prime n(despite it being better IQ)....needed fast AF so that ruled out 80-400VR (yeah realise its fast enough on D3/300 for predictive sport)...couldnt afford the lens I wanted at this stage (Sigma 120-300 2.8)....and couldnt hold out any longer for an upgraded 80-400.....so the reviews here prompted me to go for this lens and not disappointed at all !reviewed May 27th, 2008 (purchased for $580)
I had the older G version of this lens and that was a shocker (as an all rounder),had some reasonable captures with static subjects but the older lens couldnt hack it for sports.
So without hesitation I would recommend this lens and it was a much cheaper alternative........!
