Carl Zeiss Jena Flektogon 35mm f2.4 --- Bokeh

Another quirk of this lens is the slightly basic aperture design. Unlike modern Zeiss designs which have lots of blades to create a near circle at all apertures, this one only has 6. Wide open is a nice circle. Stopped down it give a distinctive "Flektogon Hexagon" to highlights, which is not unpleasing. My copy at least has point around f2.8 that gives a slightly bizzare shape, which is probably best avoided.

Non highlight bokeh seems pretty smooth at most apertures
