I am SO staying away from the Rokkor 1.2s. They're just plain gorgeous, and that fact alone puts my wallet in danger.
I was lucky - got it with a Minolta film camera, and a Tamron something or other, which I likely won't bother about

. Only got the one shot so far - looking forward to seeing bokeh etc

. $100 for the film camera and Minolta and a Tamron longer lens, which I probably will try, but not really use.
It's not f/1.2 but f/2! LOL my wishful thinking .... but still makes some nice bokeh wide open.
