I have the Canon EF 50mm f 1.2L, and it's a great little lens if you want to spend a little more. With Canon offering more support to the RF format, you can pick them up for a bit of a bargain if you shop around.
I was going to attach the tech sheet, but it's too big - outside the attachment limit. However you can find the .pdf here about halfway down the page at the Canon Australia site...
