Thanks! How about an f/0.85 image!
Canon FL 55mm f/1.2 on Speedbooster = 39mm f/0.85. I just got this in from KEH...only $215 in EX+ condition, and it's definitely that - looks practically brand new with clear optics, clean snappy aperture, nary a mark on the body.
Of course, due to pixel shading, you won't get that full speed with regards to exposure (you stop getting exposure gains around f/1.1), but the optics and bokeh are still what they should be.
Very surprised that this lens seems to perform the best of all the normal lenses I've tried on the speedbooster. It has minimal softening on the edges of the frame, in areas where the other 50s poop out a bit. Gorgeous rendering, though I'm going to need to get a hood for it, as it flares like a mofo if you shoot into the sun. Interesting mounting this guy on the SB since it has a little protruding rear element...looks like the rear element of the 55 (which is larger than the first element on the SB) probably sits about 1-2mm from the SB elements.
Here's one wide open:
