>>4478480>>4478486>DPReview tests show it as having less DR than most M4/3 camerasIf you say so. DXO has the ancient A6000 with 13.1 stops vs the 12.8 on the OM-1. And DPReview's comparison shows the OM-1 Mark III looking worse than the third of a stop difference on DXO would suggest (maybe baked in Sony NR RAW).
>>4478500Other cameras have IBIS anon. m43 IBIS is better but it only really matters in certain kinds of video. Going for the OM-1 because they bothered to get IP5X involves a lot of tradeoffs especially when you can seal up a better cheaper camera more effectively with a plastic bag.
