Nikkor 1,2/50mm

This is Nikon's fastest lens currently in production. As a manual focus AI-s lens it works perfectly with every manual focus SLR made since 1959, and also works, with varying degrees of convenience, on all Nikon digital and AF SLRs. The photographic reason to get a Nikon 50mm f/1.2 is because it's the sharpest Nikon 50mm lens in production when used at f/2. It's only a half-stop faster than f/1.4, so I wouldn't worry about wide-open speed. The f/1.2 performs about the same as the f/1.4 lenses when used at f/1.4, also no big deal. At f/2, this f/1.2 lens is operating at almost peak sharpness and has no focus shift. The f/1.4 lenses used at f/2 haven't yet reached their peak sharpness, and they oddly also have a slight focus shift which makes them just a little less sharp than this f/1.2 lens when both are used at f/2.
