We took a Steinheil Munchen Magnostar 1:2.8 f=8cm VL Projector Lens off its projector and mounted it on a Nikon Z7 mirrorless digital camera, and tested and reviewed it for sharpness, bokeh and bubble bokeh quality, flare, and black and white photography.

Kinon III F=5cm Hugo Meyer & Co Gorlitz Projector Lens was made before World War II for use on motion picture projectors. Using this lens on a modern mirrorless camera creates an astonishing bubble and swirly bokeh in photography.
