Carl Zeiss

Carl Zeiss. German company specialising in the production of lenses for cameras that are distinguished by very good image reproduction.

Carl Zeiss Vario Sonnar T

Carl Zeiss Vario-Tessar

A small and powerful lens for use in compact cameras and camcorders. Perfect to capture contrasts and colours so that images are gorgeous and crisp.

CCD

Charge Coupled Device. The number of megapixels is determined by the CCD and the high resolution it manages to catch up. CCD detects light from optics and converts it into electrical current.

CD burner

A CD burner writes information on CDs: CD-R and CD-RW. There are both internal and external CD burners available for computers. The internal variants are mounted inside the enclosure of a computer, while external varieties simply connect usually via USB. Most modern computers have a CD drive with an integrated CD burner.
