10 out of 10 points and recommendedSharp already at 1.4 on my D800, great bokeh, great Body. I love this lens.Not sealed, but is not so important!
I have the Sigma, because I like the Nikkor 35mm and is too expensive. The D800 works great with this lens. The high light intensity can be fully utilized, even at f/1.4 it produces sharp images. Each aperture, the sharper it becomes more. My sharpest lens far the Macro Nikkor VR was 105. The lens makes it easy to enjoy and has the great bokeh pictures.reviewed February 24th, 2013 (purchased for $1,252)
