This is a non-moving scene... The Hasselblad multi-shot back (which is known to not handle motion AT ALL - it's made specifically for art reproduction) would handle it just fine (with about twice the resolution of the Panasonic).
Lloyd Chambers is seeing some promising results from the Panasonic even with subject movement - I don't subscribe to his site, although I'd like to, it's too expensive. I anxiously await a result that isn't behind an expensive paywall - someone other than Lloyd has got to try shooting a landscape with this monster.
It would be fascinating to see what happened if you moved an entire test chart slightly during the multishot sequence (the test that shadowblade proposed). You'd want to move the test chart slowly enough that the shutter speed dealt with the motion within a single exposure, but the motion was significant between exposures. There are three possible results:
1.) A blurred mess, which would happen with many previous systems, including Hasselblad's.
2.) A nice ~50 MP shot (the camera detected the motion and used one of the images). In this case, the follow-up test would be to move part of the test chart, in order to find out how big an area it replaces with a single image (it could be anything from "only pixels that move, analyzing every darn pixel" on up to " the whole image reverts to 50 MP if anything moves")
3.) A shot that significantly exceeds ~50 MP (it's doing some sort of computational photography that deals with the motion).
If what it's doing is either a well thought out version of option 2 (replacing only moving parts of scenes) or option 3, it's a very interesting landscape camera. If it's giving 187 MP in 90% of a scene, with 47 MP in the areas with moving leaves or a river, that's great. It's probably tripod-bound (well, it reverts to being a lot like a Z7 off a tripod, but a Z7 is a superb landscape camera itself), but Phase Ones are pretty much tripod-bound as well, with their size, weight and mirror slap. It could be a $4000 Phase One for many purposes.
If what it's doing is either making a mess with any motion or reverting to a single shot if there's motion, it's still useful for limited landscape scenarios, and of course for art reproduction and similar jobs.
The other thing we need to think about is how to display 187mp? The 50mp class cameras make stunning 24x36" prints and beg for more printer. For the first time, I ran into an exhibition space that made me wish I owned a Canon Pro-4000 (the 44" version) instead of my 24" Pro-2000. My landscapes are on display in a large Unitarian church that has enormous expanses of white wall. I really could use 40x60" prints in there, and I suspect my Z7 is up to the job (I don't think my older 24 MP files will go that big). How many spaces like that are there? And, if I'm right that the 50 MP class cameras make those prints, how many spaces are there that want even larger prints?
