Lens nerdery today. These are snaps taken by an old soviet era projection lens the #35KP 120mm f1.9. This is the 4 element #Petzval version. In the reply you can see the lens - it's huge. I adapted it with a 3d printed adapter in two parts. The lens holder screws into the camera adapter to provide focus. It's wild - and the adapter needs more work.
