Mamiya Sekor-C PL Conversion

With the onslaught of digital cinema formats that exceed the standard 24x36mm image frame, Duclos Lenses has developed a conversion procedure for the Mamiya Sekor-C prime lenses which incorporates an ARRI PL mount and other motion picture standard features. 

The Mamiya Sekor-C primes are a unique lens that offer outstanding image quality and a large image circle in a very small form factor. Suitable for 8K Vista Vision sensors, these vintage lenses are an excellent match for ultra high quality production.

This particular mount conversion applies strictly to the Mamiya Sekor-C line of lenses. As with the rest of our modifications, each piece is a la carte. We offer the following add-ons for the Mamiya Sekor-C lenses. 

  • ARRI PL mount conversion - $495
  • Aperture de-click and damping - $60
  • Seamless 32-pitch focus gear - $105
  • 80mm front ring (77mm filter thread) - $75
  • 80mm front cap (for 80mm front ring) - $20

Duclos Lenses does not provide the lenses for this conversion. Lenses must be sourced and sent in. Ready to Cine-Mod your lens? Send it in to Duclos Lenses for a formal quote using our Equipment Shipper.
