I saw this on ebay and put a a low bid out of curiosity. Anybody know about this arrangement? 
The aperture has a declick button on the bottom of the lever. Which is cool for video. I can't figure out what the plate next to the mount does. It rotates but doesn't seem to be connected. Very unusual lens IMHO.

Can't quite figure what it's all about, but the "central" bayonet looks awfully like the original Exacta mount as used by Topcon. If I remember correctly, this was further adapted by Topcon to provide extra functionality, hence the secondary "outer" bayonet. If I'm correct, the button on the side is an extended shutter release button for Topcon and Exakta SLR's and performs the semi-automatic aperture stop-down function when pressed. |

Ah yes it dawns. The lug on the side is to mount the light meter device!

So how does the stainless base plate interact with the light meter? It rotates on my lens around 270 degrees. There is a slot cut out which must interface withe the meter somehow.

The plate looks like some type of lens mount. Maybe one of the Cine lens mounts? Many of them are four-lugged breech-lock mounts. Or maybe a custom mount similar to them. That would also explain the de-clicking lever.
The meter mount is not likely related to the alternate lens mount! |
