Have you considered the Samyang/Rokinon primes? They manual focus, manual aperture, but they're supposed to be quite sharp, and wallet friendly, while being quite nice and fast. The 35mm f/1.4 is like $500, and the and 85mm f/1.4 is $300. Obviously you don't need the wallet friendliness, but they're supposed to be excellent lenses if you don't need AF. The 35mm is supposed to be on par with the Canon L.
