The ZIF (Zero insertion force) socket is useful for developers as it allows for frequent, easy sensor removal at the turn of a lever (zero force).
Connectivity - Uses Socket 604 BGA see https://en.wikipedia.org/wiki/Socket_604
Power - The CMV12000 has a 4W continuous peak power consumption. There might be short higher peaks when training LVDS channels to initialize the sensor communication. For still images you can operate the sensor with largely reduced IO (number of LVDS lanes) which in turn should also reduce power consumption.
History - apertus° offered three different sensor options during the camera's crowd funding campaign; Super35, Super16 and 4/3rds, and as almost 90% of the backers opted for the Super35 sensor its respective module was developed first. The camera uses the ams Sensors CMV12000 .
