Epson, Nikon, Canon, Fuji, Voigtländer, Sigma . . . heck, Ricoh . . . anybody. Just give me the CMOS in my Nikon D700 nestled within a competent RF body. That's all. No zillions of "features" included just because you can. No 17 ways to autofocus, in fact no autofocus really necessary. Eliminate the back screen if you want to in order to get the price down. I never use it anyway. No 150 menu item parameters. I will confess, I never obsess over white balance. If I don't like the way it looks I can correct in PS. My camera does not have to be a portable photostudio.
Got that, manufacturers? What's that? You didn't hear me?
Oh.
