Nikon's classic telephoto — the manual-focus Nikkor-Q Auto 200mm f/4 for the F mount, compact reach.
The Nikkor-Q Auto 200mm f/4 is a telephoto prime for the Nikon F system, introduced in the early 1960s. The Q code marks its element count, and it was one of the common longer telephotos of the early F system, giving reach for wildlife, sport and distant subjects at a moderate aperture and manageable size.
This is a manual-focus Nikon F lens with a maximum aperture of f/4 and a fixed 200mm focal length, using an automatic diaphragm for full-aperture viewing. It is a medium-long telephoto operating with normal reflex viewing on the F system. Only the verified focal, aperture and mount are stated; construction details are omitted to avoid error.
The 200mm focal length gives strong reach and compression for distant subjects, with the f/4 aperture keeping the lens relatively compact for its length. It suits wildlife, sport, distant portraits and general telephoto work. Sharpness is good stopped down, and the moderate aperture makes handheld use practical in good light.
On the used market the Nikkor-Q 200mm f/4 is common and inexpensive, an accessible vintage telephoto. Inspect the elements for haze and fungus, check coatings for cleaning marks, confirm the automatic diaphragm operates, and test the focus over its longer throw. It adapts well to mirrorless as an affordable manual telephoto with plenty of reach.
