Budget M42-mount wide-angle from the Dixon's house brand, extremely affordable for adapted vintage glass shooters.
The Prinzflex 28mm f/2.8 is a budget wide-angle lens sold under the Prinzflex brand name, which was a house brand used by Dixon's, the major UK electronics retailer. These lenses were typically manufactured by Japanese optical companies like Chinon or Cosina and rebranded for the UK market during the 1970s and 1980s.
Optically, the lens performs respectably for its price point, delivering usable sharpness across the frame when stopped down to f/5.6 or f/8. The 28mm focal length was the most popular wide-angle choice of the manual focus era, offering a noticeably wider perspective than standard 50mm lenses without extreme distortion.
The M42 screw mount makes this lens adaptable to virtually any modern camera system using inexpensive adapters, giving it unexpected versatility in the digital age. Build quality is functional rather than premium, with an all-metal barrel and adequate focusing ring feel that was standard for third-party lenses of this era.
This lens holds minimal collector value but serves as an extremely affordable entry point to wide-angle photography for those shooting adapted vintage glass. Its M42 mount compatibility and low used prices make it an accessible option for experimental photographers and film camera enthusiasts on a tight budget.
