I'm guessing you feel pretty much the whole world is slapping you in the face. Come here, I'll show you what being slapped in the face feels like.
What are you talking about? What lens doesn't work with the green button?
I'm a Pentax user for 48 years, started with screw mount lenses, and I haven't got a clue what you're talking about. I use M lenses and A lenses. Maybe you could explain, calmly and without having a meltdown, what it is you're having problems with. I'm curious, maybe I'm dense but I'm just not getting it.
I guess it's lost on you that Pentax is not as big a camera company as Nikon. Maybe you should stop trashing Pentax, and go buy your beloved Nikon Df. The odds of Pentax making such a camera are pretty slim. If you hadn't already done so, I'd say, you should switch to Nikon before you get all nasty and bitter because Pentax doesn't do everything Nikon does, but it's obviously too late for that.
