I really hope Panasonic stays with m4/3. It has the economic and engineering firepower to support the system. The thing I don't understand about camera manufacturers right now is that they put out quite good small cameras, like the RX100 and its rivals, for which there still seems to be a steady market, but when they get to ILCs, they want to go big -- if the rumors about the new uber Oly are correct, it's essentially the size and weight of a small DSLR...I think it may come in larger than a Z7, though the smaller m4/3 lenses will help. And the new FF Panasonic...what's all that about? Why would Panasonic want to go head-to-head with established FF makers like Nikon, Canon, and Sony, and the well established APSC of Fuji? It seems crazy. It simply seems to me that there could be a good long-term market for a small, precise, high-quality mirrorless system that would look a lot like the GX8 with lenses that look exactly like the m4/3 lenses. I understand that some people need the big bazookas -- especially landscape guys and maybe sports photographers. But really, how many landscape photographers are there? When I was working for a newspaper back in the 90s, the paper bought F4s and then F5s for staff photographers, and the photographers were buying N90s on their own because they could do most everything the F5 could do, with a fraction of the weight. I guess we'll see. I'm really pulling for m4/3, though. In in traveling to New York last summer, I literally carried an m4/3 system in a Dopp Kit -- two bodies, three lenses, two extra batteries and a charger.
