Ah, a subject dear to my heart projection lenses. Let me post a few with the projection lenses that I have. First Angenieux. There are a series of early 35mm projection lenses by Angenieux, all of which are slightly adjustable for focal length. Three types exist, the Type 65, Type 75 and Type 86, increasing in diameter as you go up. The front lens diameter remains the same, and thus the longer the focal length, the slower the lens for each type. I don't know the entire range, but I know that they exist from 85mm to at least 140mm. The shorter ones are more interesting IMO, because of the swirl and character of the bokeh in the shorter ones.
I have a few of these, of which my favorites are the Type 65 85-90mm (effective aperture at 85mm is ~f1.3) and the Type 86 95-100mm (effective aperture at 95mm is ~f1.2). I'll post five examples from each--the first five from the 65 and the last 5 from the 86.
Added note: It turns out that the 65 with super-swirly bokeh has been modified. I had it out of its focusing mount and discovered that the rear cell had been replaced with a doublet from another lens (which one I have no idea.)
