I did try to use lens with C mount adapter , but can't screw into , looks it has bigger diameter than C mount. Any experience ?

Mine is early one 5cm f3.5 RED P.

If this lens from Kiev-16 movie camera, then it has M32x0.5 thread mount with 31mm flange back distance. It can be used on mirrorless cameras with handmade M32-M39 adapter(or just wrap thread with duct tape) over the M39 adapter.

Anyway, it's a usual Industar-50, like any other. I see no reason to mess with it.

Lenses for Kiev-16U - M32x0.5 thread and 31mm flange back,
lenses for Kiev-16C - M27x0.75 thread and 17.35mm flange back.

I think once I had an thin M27x0.75 to RMS adapter - I'm not sure if I still have it or if I sold it but I think it can be mounted easily with such an 3-adapter solution on NEX if you don't need infinity

Even good copies of the normal Industar-50 are very high-resolving in center (up to 38 lin/mm) so should be a very sharp lens.

Thank you for both! Seems Kiev-16C lens.

I did mount it with tape to M39 adapter try it at room light handheld, wide open.

Hello,

I encounter the same "problem".
The fact is that there are sellers on eBay that describe these lenses as C-mount. But they aren't.
It's an M27 mount.

From what I see from my Industar-50 and my RO-28, there is enough space margin to remake a mount from scratch.
I think it's not so easy to do but it's possible. It requires to totally cut or remove the M27 mount and solder a C-mount on it.
The operation needs to be precise about the flange distance. As I'm about to go back in my original country soon, I won't make it right now but I'll do when I will be back there.
I don't know where we can find empty M25 C-mount. This is the hard part to find. If anyone has an idea, it would help me a lot. Wink

I think it's a lot of work for few benefit.
The Industar-50 is an Industar-50, you can find it very cheap in m39 or M42 mount.
The RO51 20/2.8 covers very few, it's usuable only on Pentax Q I think, or maybe M4/3 (made for 7.5x10mm).

But if you still want to make it, chineese seller on ebay sell cheap C mount lenses CCTV, the mount part is easy to remove. That might help you.

Thanks for the idea ! Wink

I've seen incredible footages with Industar-50 in 4K; that's why I'll invest in it !

Oh, I should have precise that's I intend to use it for movie making and not photography.

I found a solution to use these lenses ! It was so simple...

My taking camera is a modified Yi 4K+ with a back-bone ribcage.
This ribcage is a CS-mount based platform, on which I put a C-mount adapter to use C-mount lenses.
So I don't need to modify the lenses; all I have to use a M27x0.75 to CS-mount (or C-mount, as the thread is the same size) adapter and eventually use a shim to compensate the flange difference, and put it right into the CS-mount thread.

I ever tested the solution by putting the lenses in front of the CS-mount and it's OK. I just have to wait for the adapter I've just ordered.
