I will be the first to admit that if I had not gotten back into astronomy and spent a few thousand on updating my astro gear I would have strongly considered getting an EM1 II or G9 this year. But that would have been in addition to and not a replacement for my current 2 Gx8 and Gx85 cameras. I've bought a lot of bodies since I got my first digital (a Nikon 775 when they first came out) but I replaced many on each model update. I have no desire to do that now. Kind of like hitting deaccelerating from 100 to zero. I have one more major astronomy purchase (new mount) to get this year and then next year I will add either the Oly 12-100 or a new body but still keep my current bodies. It reminds me of my film days when I never got a Nikon F because for what I did my 2 Nikkormats and Mamiya Press 23 did all I needed. So here is a very simple poll - has your camera body replacement time frame changed : Shorter Same Longer.
