I'm admittedly biased towards Olympus and now OM Systems, as it was the original OM-1 that was my first camera which I used from 1979 to the mid 90's, when I bought my first Canon rebel. Bought my first digital Olympus in 2014 and especially after buying the E-M1 mark II in late 2016, kept waiting and hoping for Canon (or really any brand making FF cameras) to make a camera that I felt was as good and versatile. Took a few years for other brands to get focus bracketing and in-camera focus stacking, which I use often. Still waiting for Canon to add in-camera AF limiter functionality. I don't know if anyone else has that, and that, to me, is a game changer for Bird photography, especially Birds in Flight. It really annoys me that the internet has so much anti-Micro Four Thirds bias. The OM-1 and the Olympus digital cameras I have owned prior, have all been my most used cameras, despite owning both FF and APS-C cameras from Canon and for a brief time, from Nikon as well. ( Also owned - very briefly - the A7 and A7 II from Sony, but they barely count as being cameras!). I hope OM Systems can survive.
