All! I won't be getting a CSC regardless of who makes it. For my high quality camera, I want an optical viewfinder. I've always wanted an OVF. I'm no luddite though, I recently got a Sony RX100III because it has a EVF, as my previous compact (Canon S95) doesn't. The EVF looked great in the shop, but out in the real world the experience isn't as good as I expected. I know there are better EVFs now, as this camera is a few years old, but the OVF is what I and, I expect, quite a few others still want. There may come a point where an OVF is not an option, but I think we are many years away from that yet. And anyway, I only got my new DSLR last year. It could be the last high quality camera I get. I don't need/want anything better atm.
