Kyu-hachi TABATA’s self made sky-camera,
made out of a 16mm KMZ Zenitar f/2.8 fisheye, a central shutter, and a 6×6 Zenza Bronica back.
It’s a beautiful piece of workmanship and a very inspiring project for me too. He states the lens projects a 45mm circle requiring a 6×6 back to be captured entirely.

“The lens is an MC Zenitar Fish-eye 16mm F2.8 This lens is a diagonal fish-eye. So, I thought if the film size expanded to 6×6, the photo frame also expanded to full-circular fish-eye.
The lens mount of Zenitar is M42, so, simple screw mount. Then I made a very thin inter-ring to adapt M42 on one side and a Large format camera mount in other side.”
