Prinzflex — 200mm f/3.3 manual-focus telephoto prime lens, M42 and SLR mount fits
The Prinzflex 200mm f/3.3 is a manual-focus telephoto prime sold under Dixons' Prinzflex house brand alongside the more common f/3.5 version during the 1970s and 1980s. The unusual f/3.3 maximum aperture points to a separate optical design rather than a simple respeccing of the f/3.5 lens.
Weight, filter thread and minimum focus figures were not consistently documented across the mount fits Dixons sold this lens in, so exact numbers are omitted rather than guessed. The lens has a long manual focus throw, a click-stop aperture ring, and an all-metal, glass build typical of Japanese-made telephoto primes of the period.
The fractionally larger aperture over the f/3.5 version gives a marginally brighter viewfinder image and a touch more subject separation, though the practical difference is small. Build and optical character otherwise follow the pattern of mid-tier 1970s telephoto primes.
Less common secondhand than the f/3.5 version, so listings should be checked carefully for correct badging. Inspect the focus helicoid for smooth travel, the aperture blades for oil, and the glass for haze or fungus.
