I have been in the engineering part of digital imaging for quite a while. I understand pixel nyquest frequencies, minimum possible pixel size (we are against the wall on this one,) the fallacy of a single 16 megapixel sensor, the backend electronics necessary for image capture, PRNU, the problems with dark current and recording into the toe of the gamma curve, signal to noise ratio, and about a thousand other important parameters and problems that are keeping direct pixel photography from surpassing film photography, for a very long time yet. Erwin, the folks that read the advertising and news hype and spew vitriol at you (and probably me as a result of this) are simply ignorant about how it works and don't want to hear logic, reason, and of course, the clear and undisputable facts. Very few of these people actually understand how a silver latent image is formed, valence, the redox chemistry necessary to convert a latent image into a silver (or globule) image, and the atomic structures and sizes involved. So most of the arguments given by these folks are simply day dreaming speculation. Many of the so called "experts" are not involved in the engineering and don't have a clue as to what they are talking about. But things won't change Erwin. So just keep on telling it like it is. There are a few of us out here listening to you and agreeing with you. Jim Brick
