There are two kinds of digital cameras: fixed lens cameras and ones with interchangeable screw-in lenses, and the requirement here is for an SLR camera with interchangeable lenses. The film camera has most definitely given way to the digital camera, but in terms of design, structure and form, things have not changed that much. We feel that the time is ripe for the appearance of a wholly new camera designed specifically for the digital age. We are looking forward to seeing prototype digital cameras designed with your creativity.
