The venerable 35mm f1.4 AI-S Nikkor lens is optically unchanged since its introduction in the early 1970s. It was one of the lenses prized by photojournalists, and remains popular with them today. An excellent performer, even wide open, this lens was among the first Nikon made with its CRC lens technology, or in plain English, with floating elements, for optimal performance even close up. It was also the first Nikon wide angle lens with multicoating. This lens holds its own against the Leica 35mm f1.4 Summilux-R and the recently discontinued Contax Carl Zeiss 35mm f1.4 Distagon (However, having used both this lens and the Zeiss Distagon, I believe that the Zeiss lens is optically superior.). I am surprised that Nikon has not yet introduced an autofocusing version of this lens; I suspect that one major reason is that there hasn't been sufficient interest in one from professional photographers.
