The Canon EOS DCS 1 was Kodak's second Canon-based Digital SLR camera (a rebranded Kodak EOS DCS-1). It was released in December 1995, following the cheaper EOS DCS 3, which had been released earlier that year. Like that camera, it combined an EOS-1N body with a modified KodakDCS 460 digital back. Despite offering a then-enormous resolution of 6 megapixels, with a relatively large APS-H sensor, a number of technical issues (together with its 3.6 million yen price point) meant that it never became a very popular camera outside of a few, very specialized roles.
Although the sensor was much larger than that in the EOS DCS 3, the DCS 1 had a lower fixed sensitivity of ISO 80. The large image size resulted in a burst rate of just over one image per second for two images, followed by an eight-second delay whilst clearing the buffer. A typical contemporary 340MB PCMCIA card or IBM Microdrive could store 53 images. In common with the rest of the Kodak DCS range, the EOS DCS 1 could not produce JPEG files in camera.
