What is the camera sensor size, i.e., the width and the height (in mm) for the default camera in the Phantom-4? Also please mention the exact focal length of the lens used in the same camera.

The camera sensor is 1/2.3 inch and image size is 6.3116*4.7492mm.
You could check it's spec on DJI website as well: http://www.dji.com/phantom-4/info#specs

Thanks.
You mentioned the image size as 6.3116*4.7492, but I guess it should be "sensor size" and not the image size....YES??

Moreover, the lens focal length is mentioned (on the DJI website) as 20 mm (35 mm format equivalent). Please clarify we should take it as 20 mm OR 35 mm.
