Clearly, the advantage of the MFT 2x crop factor comes into play if you crop all, or most of your images, as is the case with me. Obviously you understand that if you crop a FF image from the R5 II - or any FF camera - to the size of the MFT image or smaller, than the OM-1's 20 MP sensor totally out-resolves any and all Canon and Nikon FF cameras, and is about the same as the R7. If you have used both the OM 150-400 and the Canon 200-800, then any comparison is a joke. Basically a top-level pro lens with a very good consumer lens. The OM lens is definitely better, in my opinion, than the excellent Rf 100-500, too. The AF subject detection and tracking is definitely on par with the original Canon R5, R6 II, and better than the R7, all of which I have used. Pre-capture is better than any Canon, FPS options are higher, and the stacked sensor has a very fast read-out speed. OM's IBIS is still as good as anything on the market. It is true that OM Systems is basically a niche company now, which is unfortunate. It is difficult, in a world where the internet influencers essentially dominate the marketing opinion of consumers, for them to compete, since we all "know" how FF is the only way to go if you are a "real" photographer.
