10 out of 10 points and recommendedSmooth Operation, Sharp Images, Reasonable BokehHeavy, no VR
I have been impressed with the image quality. I wish it is better at 2.8 but you can't have everything and still keeping the price and weight reasonable.reviewed March 8th, 2013 (purchased for $1,600)
The auto-focus is fast on my D800 and the images are tack sharp from f4 and on. Images taken at 2.8 is a little soft but good enough for portrait.
