If you want to have a sensor that can do a global shutter, what you need is 2 identical sensors on a single silicon waver, one half being shielded from receiving light. At the shutter reset, the info from the light receiving part of the sensor is duplicated on the non light receiving part of the sensor and the info is read out in rolling shutter fashion from the non-light receiving one. Aside from the global shutter capability you will also gain Dynamic Range by processing the image this way.
The larger the sensor, the harder to manufacture.
IF Epic has a global shutter, it will have a sensor TWICE the size and at least twice the manufacturing cost for the sensor. Hence the higher price tag. This small but important step in image quality gain will be worth it to many people, including me.
And Big T you obviously haven't tested the Dalsa Origin since it is truly a 4K camera of the highest quality and records uncompressed RAW 4K Bayer data to an S2 or a Codex and NOT a deck as you falsely claim. Educate yourself before you make false statements please :angry03: .
florian, what you're talking about is a frame transfer ccd. it does not by it's nature have any more dynamic range than other technologies. it does have advantages over interline ccds but its not necessarily an ideal technology either. it can't do high frame rates and requires a physical shutter.
