Nikon Nikkor 85mm f/1.4 AI-s

TelephotoMount: Nikon F85mmf/1.4 – f/16
Introduced: 1981

Nikkor 85mm f/1.4 AI-S is Nikon's legendary fast portrait prime — widely cited as one of the finest portrait lenses ever made for any system. The 85mm focal length is the canonical portrait focal length; the f/1.4 maximum aperture provides the shallow depth-of-field that defines the modern portrait aesthetic. The AI-S version is the manual-focus realization of the design that later became the AF-D and AF-S Nikkor 85/1.4 lenses.
