Kodak DC20

The Kodak DC20 was an early digital camera released by Kodak in 1996. It had an MSRP of $299 when most other digital cameras at the time cost well over $1000. Needless to say, the DC20 only had the most basic features of a digital camera. It has no LCD. It comes with only 1Mb of internal flash memory which can only store 8 or 16 images, depending on image quality. It does not support external flash memory. It has no built-in camera flash. Its CCD sensor has a maximum resolution of 493x373. It has a fixed focal length f/4 lens which is equivalent to 47mm for standard 35mm cameras.

With physical dimensions of 31mm by 102mm by 61mm, the Kodak DC20 was the first ultracompact digital camera. Its sleek compact size will remain unrivalled until the release of the Canon Digital Ixus
