A fast ultrawide lens that is dead sharp in the corners at 50mp doesn't exist.
Your best bets will be the Otus 28mm f/1.4 ( not really wide ) or the Leica Summilux 21mm f/1.4 ( on Sony Alpha ).
Even then - these lenses will still have lots of vignetting at f/1.4.
Alternatively - go down with your megapixel requirements.
