I had better outline my camera history in order to provide you with a balanced view. I purchased the original OM1 back in 1975 and since then have owned 10 Olympus cameras. I currently own 2 OMD - S/Olympus OM1 bodies plus a 300mm f4 + MC14, MC20, 40 - 150mm f4, 60mm f2.8 macro and 14 - 150mm II. I shoot wildlife almost exclusively, and have to say that from my perspective, the OM1 is the best wildlife camera on the market at this time. I must reiterate, that this is my personal view. For perspective, I part exchanged my Olympus EM1X and EM1 mark III for my two OM1 bodies. Prior to that, I owned a Sony A9 and Sony A7R4. The OM1 AF speed and accuracy are truly brilliant: and CAF + TR + bird recognition is simply amazing. The 5.7 million dot OLED EVF is excellent and the new LCD back panel a vast improvement over the old one. Though 50 fps sounds a bit of a gimmick (and I did not bother to use such a high frame rate for a couple of weeks), I find it to be fantastic for birds in flight. I have not moved off SH2 (50 fps) for BIF, as it enables me to choose the best wing beat captures. Low light performance is really good and the images appear to be sharper, thanks to the new sensor (though that is subjective, I suppose). Pro Capture is just marvellous, as are in camera focus stacking and focus bracketting. The updated in camera ND filter also looks very good. I reckon that if you purchase an EM5, you will end up kicking yourself for not choosing an OM1. But, the OM1 is not for everyone. I purchased two of them because I believe OMD-S has targetted wildlife and, to a slightly lesser degree, sports photographers with this camera. It therefore suits me perfectly. But I suggest that you consider your genres of photography prior to making a final decision. I wish you good luck regardless which camera you choose.
