This is an updated version of the Disc 4000, the bottom tier of Kodak's disc series and was introduced in 1984 and discontinued in 1987. According to Kodak's website, there's no difference in the specifications between the old and new models. The only real difference I can see is that this has the folding protective cover, which the 4000 model lacks. So really it's more like the 6000 model, except that they retained the bare-metal finish instead of black plastic all the way around. The lens consisted of 4 glass elements with a focal length of 12.5mm at f/2.8, offering a 58° angle of view. The shutter speeds are 1/200 sec f/6 in daylight and 1/100 sec f/2.8 with flash. Other features are automatic film advance, sliding close-up lens, automatic exposure, built in flash, built in twin 3V Lithium battery set, permanent front cover attached, and it came with a handy carry strap. According to Kodak's site, this was badged as the Medalist I also.
Kodak disc cameras, manufactured by the Eastman Kodak Company, Rochester, New York, USA, were introduced by in the USA in June 1982 with the Disc 4000, 6000 and 8000 models. At the same time an international model, the Kodak Disc 2000, was introduced but this was not available in the USA. All four models reached the UK market in September 1982. Consumers failed to take to them in the way Kodak had hoped. Images were often described as “acceptable” but never exceptional. With sales falling, Kodak ceased camera production in 1988, and film production in 1998. Over the years of production Kodak made the disc 2000, 3000, 4000, 6000, 8000, 3500, 3100, 4100, 6100, 3600, and Hawkeye disc 7000, Medalist I, II, and Tele. Also the Kodak Tele disc, Kodak Challenger, Tele Challenger, and Kodak 460, 470 – both premium models.
