+1... I'm sure Phase one & Leaf dealers wouldn't...
I'm also sure that if you had a direct comparison with a "fat pixel" multishot MFDB you would change your mind on the margin of the difference... but this later one the dealers wouldn't like to discuss twice as much...
I've had a couple of Blad "fat pixel" multi-shot backs and have used the Sinar 54 M. Sure, CCD fat pixel sensors render a different look. Is it better? It kinda depends. ... I like the dynamic range, higher ISO, workflow, and the versatility of the Oly way more than MFD. I once earned a living photographing and reproducing fine art. My businesses depended on MS technology. My studio was equipped with a CF39-MS, H2F, several HC lenses, and a pancake camera/Schneider 72mm digitar + electronic shutter. That MS setup had to be tethered to a workstation that included an Eizo Color Edge monitor. The copy stand alone weighed 400 pounds. That was very demanding/fussy work.
The Oly was never intended for that type of operation.
I would not ever have dreamed of taking a "fat pixel" MS kit out into the field, especially at night and in inclement weather. The Oly premium and Pro lenses are champs. I hated the Hasselblad HC 35mm and the HC 50mm Mark I.
Even though the Oly employs a MFT 16 MP sensor, the single-shot files are nice so long as the ISO stays at 200 and the better lenses are used. I've made some 24" X 32" prints that are tack-sharp, noise-free, and really pop.
