Why not. 4k chip, Beyerpattern so 4K/4 for RGB+G then interpolation up to 2k. You realy cant judge the picture of the camera from a internet stream, you have to watch it on a full HD tv or a cinema to realy see the difference to a real 35mm film camera or a arri d21.
the only thing what you can judge is the field of depth, but you get the same picture quality with a nikon d90 for internet videos....
