E427-i

The sensor of the E427-i is an 11 megabytes, 4000 X 2700, full 35mm form factor (24mm X 36mm) with integrated electronic shutter.   Because it includes an integrated electronic shutter and live focus, it can be a complete camera system with the simple addition of a 35mm lens.   Its 11 million 9-micron square pixels offer excellent dynamic range and sufficient resolution for a range of applications such as institutional portrait photography where modest cost, robust design, low maintenance cost, and long life are priorities.
The E427-i can be supplied in stand-alone configuration with integrated 35mm F-mount lens adapter, or in a very flexible configuration which enables both 35mm lens adapter and adaptation to technical and medium-format camera bodies.  It is available in both color and monochrome. 

Interface Plates are available for a range of technical cameras and medium format camera bodies.
