9 out of 10 points and recommendedSharp, lightweightNone
Sharp! Useable even wide open in corners on full frame (D3). Tack sharp everywhere from 5.6.reviewed June 21st, 2012 (purchased for $166)
Good contrast. Less prone to flare than my 28mm prime.
Tiny and lightweight. Substantially smaller than my Nikkor 28-200. And better optically.
Negative: Won't replace a hammer on the construction site, but consider that it was designed to be light weight.
This is a perfect all-around lens for full frame bodies.
