Not a Hologon ...

... but it has a diagonal angle of 103 degrees. I bought an Agfa Lebox panorama some time ago. It has a 17mm-lens for pseudo-panoramic-photos. I disassembeled it and found, that the lens is mounted in a cylindrical piece of plastic. So i drilled a hole in an old screwmount bodycap, taped the lens in, glued an aluminium-ring onto the front and taped some housing for the finder. The finder is panoramic, so I have to guesstimate the framing. I think it works nice on my Zorki 1 - and the cost were just 10 Euro.

Petronius,

I was thinking about doing just that when the camera first came out as the Konica (the camera part of Agfa version was supplied by Konica), and just that I do not have the resources to get it mounted, let alone mounted properly with the lens placed at the right distance from the film plane.

It is interesting to see the lens is a reversed telephoto design, and of course the film plane was originally meant to be curved rather than flat, which explains some distortions towards the edge of the frame.

I ended up making the Konica camera carcass reloadable instead (same goes for the others such as the Fuji and Kodak versions.

Seele, I decided not to mind the curved film plane. The more important thing for me was the ability to change shutter speeds, namely when using the lens on my FED 5V.
