Canon doesn't make a split focusing screen for the 6D. Why in the shitting fuck not? I have this manual lens, because it fucking rules. I realize I can use live view, and zoom way in or whatever, but that sucks my faggot balls to do in a pinch. If I could just have a fucking oldschool split focusing screen in the viewfinder, I could stop being such a fucking pussy about taking pictures with a manual lens. Is there a decent aftermarket alternative?
