RL3di Technical Camera

$6,083.00 Sale Save

RL3di is a multi-format performer, optimized for wide-angle photography using 4x5 film, or for extended stitching using a digital back. Our professional-grade technical camera has been designed for the photographer seeking unmatched precision and control.

The RL3di features a finely pitched helical focusing mechanism, noted for its precision movement and smooth positive friction that reduces focus errors from accidental bumps. What sets the RL3di apart is its geared axis tilt seamlessly built into the camera body, allowing tilt or swing movements when using ARCA-SWISS R-mount technical lenses, 23 mm to 210 mm.

With versatility in mind, RL3di can also be paired with a digital or roll film back, using ARCA-SWISS 6x9 adapter plates and reducing adapter.


  • Integrated helical focusing with bayonet lens mount for ARCA-SWISS R-mount lenses
  • Gear-driven, self-locking micro-metric controls for precise adjustments
  • AIP (all-in-plane) rise, fall, and lateral shift - all X/Y movements are independent, made on the image plane with the lens remaining fixed, ensuring no change in perspective
  • Integrated self-locking axis tilt compatible with R-mount lenses 23 mm - 210 mm
  • Supplied with resin hand grips with an option to extend
  • International Graflok 4x5 ground glass back with integrated fresnel
  • Camera mounting foot - monoball®Fix with Classic adapter
  • Mount to a tripod or use handheld with the VarioFinder accessory
  • Modular and expandable with optional accessories
