Review of the Nikon NIKKOR 200mm 1:4 Ai-S Lens (f/4).
This lens was introduced in 1981 and discontinued in 1996 — a long run. It replaced the Ai version with a slightly smaller and lighter package. About 81,000 units were produced.
Since the considerably larger NIKKOR-Q•C version, the optical design was improved to 5 elements in 5 groups (from 4 elements in 4 groups).
This lens has a 205° focus throw, 9 bladed diaphragm and two meter closest focusing. Compared to the plastic lenses of today, its all-metal design is a joy to use. It takes 52mm filters which do not rotate as the lens is focused. It features a built-in hood and, like all Ai-S lenses, is multicoated.
The bokeh from this lens is good/not too distracting.
Sharpness is high, but this lens does exhibit some color fringing. Notice that these images are at 3:1.
