The AF-S NIKKOR 24mm f/1.4G ED Lens from Nikon is a precision FX format prime lens with a natural wide angle of view designed to deliver sharp and distortion-free images. It is also compatible with DX format cameras and provides a 61 angle of view when mounted to a DX camera. A fast maximum aperture of f/1.4 is very effective in low light situations and provides exacting depth of field control. Twelve lens elements in 10 groups including 2 Extra-low Dispersion (ED) and 2 Aspherical lenses create high-contrast images with minimal chromatic aberrations even at f/1.4. Nano Crystal Coating reduces flare and ghosting.
