Is it possible to mount any lens on the Red Cam?

As a small experiment i would like try mounting some old Super 8 and Bolex 16mm lenses on the Red Cam.

I am interested of this combination of the old and the new. And how this would effect the quality of the image.

Any ideas or photographic examples of what can be achieved through this technique would be greatly appreciated.


many thanks

I'm pretty sure you would have to engineer a face with the c-mount built into it, to replace the face of the Red with the PL Mount. And you would have to figure out the right flange focal length to get the correct back focus for those lenses.

But it would pretty much defeat the purpose because a c-mount lens won't be able to cover the entire 4k frame. You could try 2k, and probably have to zoom in on the frame in post...but at that point, why shoot with the Red?

Looks like you can use a C mount if you convert the RED to the IMS mount. People do use the RED in window 2k, I suspect more on documentaries than drama work.

Downside is that RED currently say that the IMS voids their warranty, but a number of RED owners are expressing an interest and I expect, as their warranty period, runs out quite a few will convert their cameras. However, most of these people are interested in using stills camera lenses as well as PL mount or even BNCR mount cine lenses rather than C mount.

C mount flange focal distance is 0.690", PL is 2.047". Red's OLPF is fairly far from the focal plane, that might also be an issue in making a "C" front for it. If the back element extends deep enough on a "C" lens, it might hit the OLPF.
