The Casio Exilim Card EX-S100 is a 3 megapixel digital camera with a 2.8x optical zoom lens that offers a focal length of 36-102mm and a large 2-inch LCD screen. On paper at least. In reality it is a super-compact, super-thin digicam that really has to be seen to be believed. Casio’s Exilim Card range of digital cameras has long been known for delivering incredibly small and slim models that are little bigger than a credit card. The Casio Exilim Card EX-S100 is no different with dimensions of 88mm (W) x 57mm (H) x 16.7mm (D) and weighing just 113g without the battery and storage card fitted. All of this is housed in a stylish and hard-wearing metal casing.
