The Rollex-Patent system was widely regarded as one of the most reliable
rollfilm converters of its era. Its mechanical construction features smooth-running rollers, stable film plane positioning, and tight light seals. This ensures proper flatness of the film during exposure – essential for achieving the sharp, crisp results large-format lenses are capable of producing. Because the back uses standard 120 roll film, photographers can enjoy affordable, readily available film stocks including color negative, black-and-white, and various specialty emulsions. This makes the cassette an incredibly practical choice for photographers who want to shoot large-format optics without the cost or inconvenience of sheet film.

⭐ SHOOT MEDIUM FORMAT WITH YOUR LARGE FORMAT CAMERA

With this cassette installed, your 9×12 camera becomes an adaptable medium-format powerhouse:


• Capture 8 exposures of rich 6×9 negatives
• Utilize large-format lenses and movements
• Enjoy lighter, more portable shooting
• Use widely available 120 film stocks
• Get more shots per outing with less weight

This combination makes the Rollex-Patent back a favorite among landscape photographers, portrait artists, architectural shooters, and large-format enthusiasts who appreciate versatility and efficiency.

⭐ DURABLE, ALL-METAL CONSTRUCTION

Built with classic European engineering, the cassette features a robust metal body, reliable winding knob, strong rollers, and a precisely machined film gate. The internal mechanism advances the film smoothly and evenly, while the pressure plate keeps the film perfectly flat. Decades later, these rollfilm holders remain highly collectible and fully functional when properly maintained.
