Cmount lenses for red scarlet

[Evaan Kheraj]

Hello,

Wondering if anyone knows of the best adapter path to getting a cmount lens onto a scarlet, cheers

Here's one on ebay

I have no idea which lenses will still be focusable when in it, or have iris rings reachable...
I also bet some will not have infinity focus
and others will not have enough space behind the mount to clear the olpf.
This is a bad idea for zoom lenses, as their unsupported weight will deform the mount
Lastly, a lot of C-mount 16 lenses do not cover 2k
However, its only $99 plus shipping..

cheap, but will not give you infinity focus.. macro use only.

Compared to the original RED One, the setback of the sensor within the casework seems deeper. The eBay mounts linked are simply designed and have a deep shoulder. With a custom fourscrew EPIC/SCARLETT mount with a stepped shoulder, you might get away with using the small diameter bodied turret lenses for the old Bolexes like the little winecap sized Schneider-Kreuznachs. I checked a set on the SI2K and their performance was very, very ordinary on the sharpness numbers.

Assuming there was a way to mount them at correct flange distance from the sesnor, accessing the lens controls within the necessarily deep tunnel would be another matter. The c-mount lens flange face is 17.5mm from focal plane. The PL is 52mm, the Canon 44mm or so. As you can observe from the eBay images, the setback for the c-mount in both the PL and Canon adaptors does not appear deep enough. There are very few c-mount lenses which throw a 25mm diameter image circle so it would be 2K only, even then with a chance of a vignette or portholing from the wider lenses.

Unless you specifically want a distressed look you cannot replicate in post, you are better off dealing with the ARRI standard, ARRI B, PL-Mount generations of 16mm/Super16mm prime lenses.

At 37mm or so flange to focal plane, old CP-mount/Aaton-mount 16mm/Super16mm lenses might also be impossible to mount to the deepset EPIC/SCARLETT except by purpose built fourscrew mounts. Fortunately, many of these lenses were designed for a range of cameras with cutom rear sub-assemblies or adaptors for individual camera types. It is not cheap. No custom one-off work is but many of these lenses can be remounted by a proper lens techs. Ken Hale of Whitehouse AV has PL-Mounts for the CP Ultra T* family of 16mm lenses and the Angenieux 17.5-70mm compact zoom. I imagine Visual Products can provide a similar service.

If it was worth doing, Mr Optitek would surely have done C-mount adaptors for PL and Canon, or four screw special mounts already and properly.
