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.

Meyer Gorlitz Kinon Superior f=5cm Projector Lens is yet another vintage lens that we're testing and reviewing for bubble and swirly bokeh, and sharing the results.

We tested Laack Anastigmat 1:2.5 f=7.5cm Ihagee Projector Lens, an 80-year-old vintage lens on modern mirrorless cameras and tested the results for bokeh, character, and other qualities.
