Jenoptik is a long established and highly regarded East German optical manufacturer.
However, it doesn't (or hasn't) in the past produced its own digital cameras, but rebadged products from other manufacturers.
Models it sold 12-18 months ago were mainly rebadged cameras produced by the Minton Optical Company of Taiwan - the Jenoptik equivalent was about 50 per cent more than the Minton versions on sale in the UK. However, very few retailers stocked the Minton models.
Don't be put off by rebadged products - it's very common for all types of computer systems, components and peripherals to be rebadged as it is impossible for one manufacturer to actually make everything it sells.
Many of the top Japanese digital cameras are rebadged products carrying a leading brand's name; my own Minolta Dimage E203 could also be bought as a Konica EZ200 with slight cosmetic differences.
Other examples of rebadged items from well known brands include CD-R, CD-RW, DVD-R and DVD+R media; video tapes, CD and DVD rewriters, graphics cards, monitors, mice, keyboards, scanners, speaker systems, webcams and so on.
