9 out of 10 points and recommendedSharp at f2.8, excellent micro-contrast and color transmission.Not f/1.8
The modest price of Nikkor 10mm f2.8 belies it's excellent optical qualities that noticeably exceed those of the 10-30mm f/3.5-5.6 in all aspects. Sharpness across the frame is very good and distortion is nicely controlled. Micro-contrast is excellent where the 10-30mm is lacking.reviewed November 20th, 2012 (purchased for $99)
If you don't have the 10mm f2,8 lens for your Nikon 1 camera, your missing out on the larger aperture that allows PDAF focusing in dim light, (3 EV), and the better image quality it affords over the 10-30mm lens.
