85mm

Nikkor-H 85mm f/1.8 lens from c1971. Nikon stopped making this lens when they introduced the AI standard in 1977 and substituted a smaller f/2 model. It was not as highly regarded as the old model and in the fullness of time the original was resurrected in AF form in 1987. Coincidentally the AF version was the one I used to photograph the old timer above.
