Late Nikon "K" non-AI Lenses

Last non-AI Lenses: "K" style
Circa 1974-1977


200mm f/4, 135mm f/2.8 (older version), 135mm f/3.5, 43-86mm f/3.5
85mm f/1.8, 55mm f/1.2, 24mm f/2.8, 35mm f/2.8
28mm f/2.8, 28mm f/3.5, 50mm f/2, 50mm f/1.4 (newer version)

K lenses are like mullets: AI in the front, non-AI in the back.

These are interesting transitional lenses.   They drop the letter marking for the number of lens elements, and they are multicoated but they drop the "·C" marking.  They are non-AI lenses, but besides the old style aperture rings they are styled like the later AI lenses with rubber focus rings.   I get the sense that people who collect older non-AI lenses don't like the modern aesthetics, and people who like the later lenses don't like the non-AI mounts.   K lenses are considerably more uniform cosmetically than the early lenses: mostly black, silver grab ring, rubber focusing grips, and knurled aperture rings. In any case they are often a cheap way to get the same optics as later AI lenses.  When they are cut to AI, or even better, upgraded with a factory AI kit, they are basically indistinguishable from the AI lenses unless you check the serial numbers. The only exceptions are the 35mm f/1.4 (K stops down to f/22, AI to f/16) and 105mm f/2.5 (K f/32, AI f/22).

Some lenses have both C and K versions, some lenses only have C versions (usually because they were discontinued, like the 45mm f/2.8 GN and 200mm f/4 Q), and some lenses only have K versions (usually because they were a new design).  A few lenses (mostly fisheyes) skipped both versions, probably because they came multicoated but predated the C marking.  However, the 180mm f/2.8 had single coated, multicoated and AI version with no K version, and the 300mm f/4.5 has single coated versions and K versions with no C marked versions.

Some K versions focus closer than their earlier versions: 28mm f/3.5, 50mm f/2, earlier 50mm f/1.4, 55mm f/1.2, and 85mm f/1.8.  The 24mm f/2.8 and 28mm f/3.5 also got upgraded to 7 aperture blades.

As always this is a strictly worse version of Photosynthesis.
