At this point M43 is, in my neck of the woods, basically a video format anyway. I do on-site videography (my schtick being "we can run a four-camera live show from anywhere I've got Ethernet and power") and all my cameras are M43 because they hit a great spot on the price/quality curve. (Sony's APS-C cameras are very respectable too, but the glass is pricey.) Never used an Olympus, never understood the point of one.…
Never used an Olympus, never understood the point of one. I see a connection there :). The Olympus cameras are extremely capable, yet small in size. An E-M10 or E-M5 have a tiny body and there are extremely compact lenses to match them. Yet, despite the smaller sensor (compared to 35mm) you don't sacrifice much of image quality (or none at all for many tasks) due to the excellent lenses.
(Apparently IBIS used to be a differentiator, but as I have learned in this thread, the G9/GH5 have it and retain their lens OIS too.)
