Input:
Fantastic lens, especially given the price. Nikon's cheapest lens is also one of their best lenses. Used on a Nikon D90 and D7000.

Performance:
The photos that this lens produces are incredible. Dof is fantastic, and the bokeh is beautiful. Sharp images all around. I keep this lens on my D90 at night because the lens is small and has exceptionally good low-light performance.

Design and Quality:
Quality of the lens construction is good. Not as tough as some of Nikon's higher end lenses, but I have no worries about this lens breaking. Since it is a prime lens, there is no zoom ring, only a focus ring. The lens is very small and light, and is easy to carry around.

Overall:
Greattt buy. Highly recommended. If you've never tried a prime lens before, they're definitely worth it. Photo quality is just never quite as good with a zoom.
