The Kodak DX3900 was announced in August of 2001 with a maximum resolution of 2160 x 1440 pixels. This 3.1 megapixels camera with a Sensor size of 1/1.8" (7.144 x 5.358mm) and a CCD Sensor has a Focal length equivalent of 35–70mm of a 35mm film camera with its 2X optical zoom. It operates at ISO 100 to 200 automatically and has maximum apertures of F3.3 to 4.5. It also has a 1.5-inch color LCD display screen and a ¾ inch by 1 inch mono LCD status display plus frame counter screen on the top of the camera. The maximum shutter speed is 1/2000 of a second. The camera manual tells you not to use alkaline batteries but to always use two AA lithium batteries or the camera may not operate correctly or at all. The camera has a built-in flash, flash ready LED, self-timer with light, built-in lens cover (on/off switch), 1.0 USB port, video out port, Kodak dock connector, compact flash memory socket (type 1), and a ¼ inch 20 thread tripod socket. The dimensions are 116 x 67 x 42 mm (4.57 x 2.64 x 1.65″). One notable feature is that nowhere on the camera does the word EasyShare appear but it has the docking port and the user’s guide proclaims it.
