Having had the 55 mm ais micro i was a little concerned about this lens with all the plastic parts, but having shot with it for a week is seems to work very well.
This 60 mm afs is very fast in its focus ability even on my Nikon D40 camera. Absolutely spot on with auto focus and easy to focus manually, also spot on.
I purchased this lens, mainly for shooting Products and Furniture in the studio as I really like shooting with a 85-90 mm FOV lens for this application and this 60 mm on 1.5 crop gives me a 90 mm FOV.
And as another FM"er has stated the flair reduction etc, is much better because of the N coating while shooting with backlighting and ED glass gives just beautiful colors. But use the supplied hood.
I most always will shoot this lens on MF and on a Tripod because of the product shooting.
So I am really liking this lens and the only thing i would change would be to have Nikon put this same N coating, ED glass etc in a Metal AIS mount CPU chipped lens. Zeiss has done it ,Nikon are you listening ? But am I dreaming now.? And by the way I could have purchased the 50mm zeiss macro but the FOV was too short for me.
All in all I give it a 10, for colors and sharpness, with reservations, because of all the plastic.
