Dear Users, I'm going to Tibet soon and I'd like to equip myself with something that will deliver a significantly better image quality than my Olympus E-M5mk2 + 12-40mm f/2.8 I was thinking... Perhaps A7ii is the way to go? Is it reasonable to wait for the announcement of A7iii? I suppose that the camera won't be out until mid or late 2017 though? Matter of fact, the size isn't such a big deal for me. I got rid of all the small m4/3 lenses (aside from the 45mm portrait lens) and kept the PRO 12-40, which is quite big anyway. I could go for a full frame DSLR. I've never owned one though, as my very first camera was Olympus E-PL1. Thus, I've always been part of the mirrorless world.
