25mm and 10mm Schneider and Angenieux C-Mount Prime Lenses for Eclair NPR

[Thomas Beach]

Hi Folks,

I'm trying to avoid purchasing a lens or two that will end up not working with my Eclair NPR and thus become unusable. In particular, I am searching for either a Schneider Xenon 25mm f/0.95 or the Angenieux f/0.95 as well as possibly a Schneider 10mm f/0.95, both in c-mount and guaranteed compatible with the c-mount receiver on the NPR. Can anyone recommend a site or camera facility to reach out to for reliable pre-purchase information?  I would be very grateful.

Someone like Visual Products would be good to reach out to.

But you could probably work out yourself if a lens is compatible. The only real issue is whether the C mount threads protrude too far into the camera body. I haven’t seen an NPR for over a decade so I don’t recall the C mount depth but you could easily measure how deep the threads go. 

I don’t recall ever hearing about a Schneider f/0.95 10mm. Some newer high speed C mounts are machine vision lenses that protrude back too far for film cameras. I wouldn’t use this for instance:

But the Angenieux f/0.95 25mm and other versions of that design should be OK:

Are there other issues you are concerned about?

The Schneider 25mm f0.95  works great on Bolex, it doesn't have that protruding c-mount thread.  It even performs well on reflex Bolex, though focusing needs care.

I seem to recall the Eclair c-mount receiver is fairly standard like on other 16mm cameras ?

Slightly off-subject, here is a lens which is not common now but may yield results pleasing to you. It has a limited zoom range so might be best described as a variable prime, rather than a zoom lens. It is not as fast as your preferred Angenieux 0.95. It will fit to and work on a Bolex H16RX5. Used specimens may have gone tight with dried internal lube so may need servicing.
