Because of their light weight and large format coverage, the Mamiya's have been rapidly growing more popular with cinematographers. This Mamiya modification was a special one for us because it is a shift lens.
Shift lenses are used for perspective control and are mainly popular for Architectural purposes.
Our technicians are highly-trained and have a wider pool of experience to draw from so the idea of pursuing modifications on a Mamiya shift lens was not too daunting. The first step is the de-click process. The aperture ring is accessed through the rear of most lenses, however, some Mamiya Sekor-C lenses require us to access the aperture through the front of the lens. This requires a more extensive dis-assembly and utter concentration.
When our technicians de-click a lens we dis-assemble and clean all components. We then apply a high-grade grease to give it that smooth cinematic feel.
After de-clicking and greasing the aperture our technician re-assembles the lens following the same steps they took during dis-assembly. Then it's time for the PL mount conversion. The first step is to remove the original mount.
Then we install our sub-mount and PL mount (all designed and manufactured by Duclos Lenses). 
The final step is to measure the lens for the focus gear. Every focus gear is custom-cut in house by our technician.
Voila! You have a modified Mamiya Sekor-C Shift Lens!

A Kowa Infrared 50mm f/1.9 came to us from a client who had a specific use for it in a more cinema-friendly application.

A bit of an odd modification, and partial at that, but still work that we're pleased to share with you...
