I've never been quite interested enough to consider the high prices of the Olympus factory housings. I'll probably get a GH5 eventually I'm more interested now in learning something about video, but I'm going to wait to see if we get any significant sensor updates first. Micro Four Thirds has kind of stalled and my E-M5 first generation still performs just as well as the Panasonic GX8.
That's really all kinds of not good enough after what? Nearly 5 years now... Yeah... I bought into Micro Four Thirds because of the potential of awesome small interchangeable cameras with awesome sensors. It seems Sony's latest RX100s come pretty damn close to the performance of Micro Four Thirds.
I don't know what I'm going to do next. Micro Four Thirds is becoming more and more like Four Thirds all the time and then Olympus has started with the pricing "Pro" lenses at the same price as high end Nikon and Canon lenses. That's never gonna attract professionals. You can't be serious trying to tell a lens with half the focusing ability for the same price as a Canon L or Nikon FX lens seriously?
