Blurry mess. So no, it isn't consistent. He does have a 30s one that is usable but the corners are blurred because IBIS can't keep everything in focus. And 30s certainly doesn't work with telephoto so I guess if you are only shooting wideangle and the light isn't changing much so you can spend several minutes trying to get a stable image where corner quality, dynamic range, and resolution don't matter then fine. Of course the guy with the $200 D3200 and a tripod can consistently take long exposure, sharp corner to corner, wideangle to telephoto, better dynamic range and higher resolution images without needing any special techniques.
Their marketing might be to landscape people but that doesn't make it a better landscape camera. Super resolution doesn't work when there is movement in the frame and any DR improvement can be replicated with exposure stacking with any other camera. You can get 14.8 stops without needing any kind of stacking with the D800. I'm sure you can make up a case where you just HAVE to use an OM-1 and NO OTHER camera can meet your requirements but if you are in a dusty location and are changing lenses, the OM-1 will still allow dust in. Plus dust will work its way into the seals and compromise the weather sealing.
