Canon is rumored to be working on a new 50mm prime lens with a maximum aperture of f/1.2. The EF 50mm f/1.2L II lens is expected to be announced in late 2015.

Canon will replace the EF 50mm f/1.2L USM prime lens with the Mark II version but this lens will come after Canon’s next prime L lens which is looking like a 35mm f/1.4 replacement. So the Canon EF 50mm f/1.2L II lens would be coming by the end of this year or in early 2016.
Currently the price of the EF 50mm f/1.2L lens is around $1,500. The bright prime optic is a high-end lens and the new Canon EF 50mm f/1.2L II version will probably have a very high price tag too.
