9 out of 10 points and recommendedExtremely sharp, great quality, ideal 'normal' lens on DX body.Some CA/purple fringing wide open
On a D2X I've found that this lens makes an ideal, if not cheap, normal lens.reviewed December 22nd, 2005 (purchased for $1,400)
If you think you've got even a hint of a back-focus issue with a D2X then this lens will show it at f/1.4! Focus accuracy is critical and it will show up any inaccuracy with your camera.
I found a surprising amount of CA/purple fringing in extreme contrast scenario's which Nikon Capture cleans up. If you have highlights that are close to over exposure then the CA will bloom. I've only really noticed this when using wide open f1.4, 1.8, 2.0.
If you are shooting f2.8 or more then the 17-55DX is probably as sharp and definitely more versatile.
Construction & quality are, as you should expect, excellent. If only all Nikon lenses were as superbly crafted.
