I notice the 50mp CMOS sensor isn't listed as being 'full frame' like the two CCD options. Same Sony crop sensor everyone else is using in their medium format offerings??

tried phase one. not really impressed. 10% better quality for 1000% the price.

I must say that I'm confused by this. It appears to be a new lens mount, but it's a 35mm lens? Isn't that equivalent to something like a 24mm on the crop, and an 18mm on the full frame? That seems awful wide for a kit lens, even from these guys.

An interesting bit of marketing. Landscape shooters have been using this rig with shift lenses for years now.

Nothing really new here as far as I can tell. They're just coupling existing gear (Rodenstock lens and Alpa camera body) with Phase One digital backs. The only thing new here is the addition of an iPhone for Live view. I'd love to try one out, though!

This sort of camera has been around for a long time.
Just a flange that connects a MF lens to a Phase One back.
In this case it is a CMOS back with OK live view, but a small 44x33 sensor just a few millimeters larger than a FF 35mm dslr.
Calling it Medium Format is a bit f an exaggeration...

Alpa is a technical camera, nothing new really. They developed FPS camera before since Copal is driving prices up and likely to stop manufacturing leaf shutters.
FPS actually takes Canon, Nikon and Mamiya lenses using adapted plate.

And if you can't, what's the point of strobes and mirrorless cameras?

And if you can't, what's the point of strobes and mirrorless cameras? I can't speak for the Phase One backs, but I can tell you how a DSLR does it.
Let's assume your screen updates 30 times a second. It doesn't matter if it does - we just need a number. So we've selected 100 ISO on the camera, and f/11 on the lens. The camera still shoots at 100 ISO, but it boosts the ISO as high as necessary(probably all the way) if order to get a reasonably bright image at 1/30th of a second, and that's the image you see for Live View.
When using a DSLR with an electronic lens, the Live View image is made at maximum aperture, so it's not usually too awful. Grainy, but serviceable. When using a lens with a manual aperture dial, this isn't possible. The image is usually too grainy for proper focusing.
So, you do the same thing you'd do with a view camera. Put a bright light in the room,open the lens to focus, and stop down to shoot. Even without a leaf shutter, the exposure from the light in the room is neglegable. With a focal plane shutter, it might be just enough to alter your WB from 'true' flash colour. With a leaf shutter, it's extremely unlikely to have any measurable effect on exposure at all, unless it's well over 1000 watts.
