Why buy this over an A7 ?
Hmmm...not a pinky near the lens when shooting, ... with a tremendous lens range.......... Leica's...
Konost...........keeping things simple!

What do I think? Rubbish because of the lack of physical controls, it would all be done via touchscreen?? On a range finder?? Need to practice my nose muscles then. Or not wanting to change ISO or for instance exposure compensation while looking through the view finder.
For the rest, nice industrial design.
The CMV20000 image sensor features a 20 Megapixel (5,120 x 3,840) resolution with 6.4 um sized square pixels resulting in an active sensor area of 32.8 x 24.6 mm (35 mm film optical format). Peak quantum efficiency reaches up to more than 45 percent resulting in a superb responsivity of 8.29 V/lux.s in combination with an excellent dynamic range of 66 dB. By means of correlated double sampling in global shutter mode, the patented 8-transistor pixel cell architecture reduces any dark noise and FPN non-uniformity of the sensor matrix. The sensor also offers an excellent shutter efficiency, a common feature of the CMV image sensor family.
At full 20 Megapixel resolution and with a 12-bit ADC resolution the CMV20000 delivers 30 full frames per second. This is achieved by using 16 LVDS outputs running at 480 Mbit/s each. Lower frame rates can be supported by multiplexing to 8 output channels only. Partial read out, windowing and subsamples modes, can be programmed to support higher frame rates. At full resolution and frame rate, the power dissipation is 1.1W. This power consumption can be dynamically controlled when lower frame rates are used.
4:3 was (and still is) also common in medium format, not only compacts. Imho, it often looks nicer for portrait oriented images.
But it's true that a 32x24mm sensor is not strictly speaking a "full frame" 35mm sensor.
I'm curious about the "digital rangefinder" instead of a mechanical one. Sadly, they don't give a lot of information about how it works...
