The Konica Revio C2 was introduced in 2002. It was the perfect modern variant of the old "vest pocket" camera concept: Not best image quality but a moderately good very small camera of nearly cheque card size. The camera was extremely flat and had a fast wide angle macro lens, an optical viewfinder, an 1.6" monitor, 14 MegaByte memory, bvuilt-in flash, and an image resolution of only 1.2 megapixels. It sucked its energy rapidly from two AAA rechargeables. It was even capable to make videos. The best was its nice metal design with sliding door as lens cap and on/off-switch.
