There's a 135mm T1.3 [~ f/1.2] Master Prime...it's 7" long, 4.5" around, weighs over 6 lbs, only covers S35 [~APS] and costs $27,500.
It's not impossible, just really impractical.
Actually there are all sorts of PL mount Motion Picture lenses that are T 1.3/1.4 etc. (T is actual light transmission wheras F is theoretical transmission based on the lens formula) But yeah, as Lee stated they are huge and expensive and generally only show up on film sets. I've worked with them and they are breathtakingly sharp even wide open and have no distortion to speak of, at least compared to lenses we are used to in the still world. Also made of metal and individually calibrated.
That being said, they are starting to creep into the high end fashion shoot field where PL mounts are being used on RED EPIC cameras to shoot stills.
