Novoflex's vintage telephoto — the 240mm f/4.5 from the German precision manufacturer.
The Novoflex 240mm f/4.5 is a medium telephoto prime from Novoflex, the German manufacturer known for precision optical accessories and bellows systems. The 240mm focal length is an unusual specification typical of Novoflex's specialty telephoto range, designed for use with their BALPRO or follow-focus systems.
The lens delivers 240mm at f/4.5 in Nikon F mount configuration, manual focus, and full-frame coverage. Novoflex lenses are typically designed for use with bellows or focusing units that provide the focusing travel rather than a conventional helicoid.
Novoflex's specialty telephoto lenses are valued for their German precision manufacturing and use with Novoflex's unique pistol-grip follow-focus systems that allow rapid single-handed focusing while tracking moving subjects. The 240mm focal length on Nikon F mount provides medium telephoto perspective.
Verify whether this is a bellows-mount or helicoid-mount version — Novoflex made both. Test focus ring or bellows coupling as applicable. Inspect element condition. Check Nikon F mount coupling. Novoflex accessories (BALPRO bellows, follow-focus unit) may enhance practical use.
