well, then you'll have to trust me--go B3 and never look back (you will only see your eye upside down and tiny if you do)

my eyes are not worth the paper this thread is printed on and i can still use B3 with 50/1.2 wide open

(nothing wrong with the stock K2 either; missed focus will be in your technique, not in the screen)
