The DM40 sports a 40 megapixel image sensor, and the upshot is that when mated with excellent optics, exquisitely featured image files are created. The large 44 x 33mm image sensor, joined with an 16 bit/channel range of colors, presents exceptional color exactness and deep 12-stop high dynamic range captures images in one single shot. The flexable back has an 80 to 800 ISO range, and sports a 6 x 7cm touch screen LCD.
