PESO: Swirly bokeh

Just a quick throwaway frame.

I had this lens from a Soviet Lomo Smena 35 laying around. It's a triplet,
40mm f4

So I disassembled it and glued the lens/diaphragm part to a 49->42mm
stepping ring, then attached that to an M42 focusing helicoid and to a Sony
FE->M42 adaptor ring so I could mount it on the A7ii.

First thing you see is how "swirly" the bokeh is at f4. Interesting look...

Here is the frame:
