Cameras are like cars. Each model is designed for a specific market segment.
This camera does not seem to fall into any of the practical categories ie sports/action, portrait, photojournalism, fashion/glamor.
A medium format camera with 50 Megapixels is not going to be used by those who want to snap images and upload them on the go because the files are massive... 30 to 40Mb.
The camera can't be used for sports events either because it does not have the sophisticated focus tracking abilities and the high iso capabilities to match the likes of the Nikon D5 and the Canon 1DX. The battery life good only for 300 images means it won't last more than 30 minutes of shooting at a fast paced event.
Pros won't use it at fashion shows because it does not look like a pro camera. Size does matter as a professional photographer. The battery life is inadequate for a fashion shoot too.
I can only conclude that it is for the snobs.
It's like wearing a Rolex or driving a Bentley.
