Prinzflex — 200mm f/3.5 manual-focus telephoto prime lens, M42 and SLR mount fits
The Prinzflex 200mm f/3.5 is a manual-focus telephoto prime sold under Dixons' Prinzflex house brand in the 1970s and 1980s. A 200mm f/3.5 was a relatively fast option for the focal length at the time, giving SLR owners a step up from slower 200mm primes without the bulk of faster professional glass.
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 era.
Compared with the Prinzflex 200mm f/3.3, this is the marginally slower but more common of the pair, with contrast and sharpness typical of mid-tier 1970s telephoto primes: usable centrally when stopped down, softer toward the edges wide open.
Secondhand examples appear regularly, often heavier and more front-heavy than modern 200mm lenses. Check the focus helicoid for stiffness, the aperture blades for oil, and the glass for haze or fungus before buying.
