Right, as far as I’m aware, only like a couple of m43 bodies (Olympus only, I think?) have PDAF, although I haven’t really kept up with m43 releases the last few years. It’s been long-requested, but Panasonic, at least, seemed to be unwilling to do it, claiming the potential for image artifacts caused by the PDAF pixels. That’s a real possibility, but they finally relented on their latest L-mount body (S5x or something?) after the previous L-mount bodies had that the auto-focus in particular being widely criticized. Perhaps the replacements to the G9 or to the GH6 will have PDAF.
