The 1 NIKKOR 10mm f/2.8 is a single focal length , CX-format wide angle lens (27mm equivalent in 35mm format) which renders sharp photos for a variety of needs, including landscapes and group shots.
The Aspherical lens element  virtually eliminates the problem of  aberrations, even at the widest aperture and it is useful in correcting distortion that is common with wide-angle lenses.

The fast f/2.8 aperture delivers detail even with low light subjects. Extremely compact and stylish, this is the lens you can take everywhere you go
