What lens do you have? And what camera body do you have? I know you have a 50mm 1.2 is it good at autofocusing or what else is it good at?

I have the 50mm 1.2 with the 5d mark ii.

My lens is good at not breaking when I accidentally hit it constantly since I’m the clumsiest person on earth. (thank god for insurance.)

It auto focuses pretty darn decent. There is a bit of a problem in the dark and with really bright back lighting from the sun but then I just flip it into manual NBD.
