Probably The Absolute Sharpest Lens Ever Made By Nikon

Nikon 50mm f/1.2 AI-S Manual Focus Nikkor LensNikon's ultra-high-speed NIKKOR 50mm f/1.2 normal prime lens offers more possibilities in low-light photography. The Nikon 50mm f/1.2 AI-S is the fastest lens in Nikon's lens lineup. This is one of three commercially made normal lenses that Nikon produced for the F mount that has a maximum aperture of f/1.2. The two others are the Nikkor 55mm f/1.2 and the Noct-Nikkor 58mm f/1.2. The Nikkor 50mm f/1.2 AI-S is the only one still in production. With it's very wide f/1.2 aperture very shallow depth of field is possible. It also provides very shallow depth images when used at f/1.2. This lens is notably superior to the previous 55mm f/1.2 design and produces a better result at f/1.2. 50mm is a terrific focal length for basic portraits, it's slightly telephoto on most cropped DSLR cameras

The people who say this lens is soft either needs glasses or the need some sort of manual focus training lessons. This is probably the absolute sharpest lens ever made by Nikon. Reading the reviews from professional photographers it is quick to ascertain this is not a casual, all-purpose len, but is a lens made for a specific, high-end niche, and 90 percent of the people would be better off with the less expensive, more automatic f/1.8 AF lens, but for what it does, it does it exceptionally well. On a D40, D40x, D3000 and D5000 all prime lenses are manual focus anyway, and relying on auto-exposure is pure laziness...skill will always trump the camera's guess any day.

This lens is built to Nikon's classic all-metal manual focus standards offering smooth focusing and rugged construction.


AI-S - The descendant of AI, AI-S lenses added a pair of mechanical features necessary for both automatic and semi-automatic exposure functions of the Nikon F4, F501/N2020, F301/N2000 and FA camera
