Another reviewer writes (and I agree): "At the first time i looked through it, was something to fall in love with easy and the first shots were exactly the same. This lens has beautiful bokeh, very good sharpness even widely opened and good color saturation. My one is the second version with the metal ring, but appears to be single coated, as it reflect violet colors from its front lens.... Color is a bit warm, but really not disturbing, i like this tone for human faces. Focusing ring is very smooth and precise, the lens itself is very well built. Series E was Nikon's first cheapo line-up. If any of todays low-cost Nikkors would turn out such performance with such rock solid and lasting build, i would be very happy... I got mine as a thrown-down one and now its one of my favorite. If You encounter one: Give it a try!"
