The AF-S NIKKOR 85mm f/1.8G Lens from Nikon is a fast, compact FX-format prime medium telephoto lens. Though optimized for FX-format DSLR cameras, the lens is equally adept at serving any Nikon DX-format DSLR. The combination of its mid-range telephoto design and a fast f/1.8 aperture make it an excellent option for shooting both still images and HD video in low light scenarios. Available light shooters will love the wide-open effect when shooting intimate portraits; in-focus subjects will stay sharp, while distracting backgrounds will melt into a pleasing soft blur. When mounted on a DX-format DSLR, this 85mm prime delivers an apparent focal length of approximately 127mm.
