"Will meet only at a bank" BAWALALWASWWWWAAAH

In the 1960s, Canon made a 50mm F0.95 (!) lens option for the Canon 7, their professional-caliber rangefinder camera. It was the fastest lens out there and coveted for years... there were even Leica adapter mounts made for it. People loved it for the "bokeh", or the way that the soft focus parts of the image (which you're bound to have when shooting wide open at that aperture, with many elements of your image out of focus) having a a dreamlike quality. The price has dropped somewhat on that one because few diehards shoot film anymore.
