The Samsung SL Series SL820 Digital Camera features a 12.2 megapixel image sensor behind a Samsung-branded 5x optical zoom lens with a useful 28mm wide angle through to a 140mm equivalent telephoto and a maximum aperture that varies from f/3.4 to f/5.8 across the zoom range. There's no optical viewfinder, with images instead being framed on the Samsung SL820's 3.0" LCD display.
The SL820 offers dual image stabilization - achieved both by raising ISO sensitivity and with a mechanical stabilization system of unspecified type. The Samsung SL820 also has a built-in flash strobe, HDMI connection and a 30 frames-per-second H.264 720p high definition movie mode. Other features of the Samsung SL820 include autoexposure / autofocus-linked face detection capable of recognizing up to nine faces in a scene, blink detection, smile detection, a "Smart Auto" mode that automatically chooses one of eleven scene modes, "Smart Album" function in playback mode and a "Beauty Shot" mode which enhances skin tones.
