Sony Japan has just announced the development of a  35mm film negative sized 24.81 effective megapixel sensor designed for SLR cameras that can capture up to 6 frames per second.
Because it is the same size as a 35mm negative, the new unnamed sensor would allow an SLR to capture 24 megapixel images with no lens multiplier factor: the focal length of the lens would be the same as on a 35mm film camera. This is especially important for wide-angle lenses; the multiplier that most digital SLRs impose (which is caused by the fact that most image sensors are smaller than a 35mm negative) means that wide angle lenses offer a smaller field of view than they do on a conventional film SLR. With an SLR built around this new sensor, the field of view would be the same as on a 35mm film camera. Read the whole article here
