The ARRI Alexa RED EPIC Sony F55 Sensor Test:

What does an ARRI Alexa, RED Epic, and a Sony F55 camera have in common? Sensors… And Allstar the gear makers who gave us the A-Mount System and the tripod / shoulder base rig for cine compact cameras have bundled together the ARRI Alexa, RED EPIC, and Sony F55 cameras for a little sensor test.

The test is intended to learn more about the characteristics of the machine, can be able to control it, to help people rather than advertising, so my next conclusion is determined depending on the measured results.
The test for the characteristics of the sensor compare interface, accessories, post process.
