"The 1 Nikkor 10mm f/2.8 is the first prime lens available for the Nikon 1 system. It's a wide-angle lens that offers a field of view equivalent to a 27mm lens on a full frame camera, a focal length that is covered by three of the four CX lenses introduced at system launch.
On paper, the lens doesn't offer much over the 10-30mm kit zoom. The minimum focus distance is identical to the zoom lens and with a maximum aperture of f/2.8 the prime is less then a stop faster than the zoom at the wide end, which features f/3.5 here. Given the small sensor size of the Nikon 1 system, the difference between the two lenses regarding depth of field potential is almost negligible. The small advantage the prime gains with its slightly larger aperture in terms of shutter speed, it loses on the other hand due to the lack of optical stabilization.
The main difference and real advantage of the 1 Nikkor 10mm is its small size and weight: it's a pancake lens. Especially combined with the smaller of the two current Nikon 1 cameras, the J1, it offers a very small package, that unlike the zoom kit is really pocketable.
In this review we will have a look at how the lens performs on our current CX test camera, the Nikon V1."
