Well, there is a new manual lens, avaliable for Nikon and Canon mounts, which is 50mm F/1.2.
It is called Zenitar 50 f/1.2 and is designed for APS-C and DX sensors. It is designed in 2014 and manufactured from 2015 in Russia, and costs like 370$.
Full metal construction.
Here you can watch it on Nikon DSLR (it is in Russian, but you at least can see how it looks)
