The Nikon 1 – 18.5mm f/1.8 is a fast aperture normal range lens designed for Nikon 1-series digital cameras. It offers users a normal angle-of-view equivalent to 50mm, which serves great as an everyday lens for shooting just about anything. The ultra-fast f/1.8 maximum aperture makes it a great choice for low-light photography or portraiture where a shallow depth of field is desired.
