Mitchell BNC 35mm movie camera
It seems to be Mitchell BNC camera. It has been modified to work with Russian lenses and accessories. So, owner got a perfect setup: great USA camera with very good and cheap Russian optics and parts.
1. Lens mount has been converted to OCT-19 to accept Konvas/Kinor lenses (there are wide range of them still available - zooms, anamorphics, fast ones, etc.)
2. Konvas mirror shutter has been installed. So, it became the great production camera.
3. Viewfinder mount can accept Konvas viewfinders - both spherical and dezanamorphing ones.
Included items are the camera itself, electric motor, and 2 of 300m mags.
Feel free to ask your questions. Thanks.
