The SZ-31MR is an extraordinary compact. Together with its outstanding 24x wide optical zoom lens (25-600mm), i HS technologies give it the power & versatility to capture movies & stills in superb blur-free quality, often at the same time. i HS draws on Olympus 16-megapixel backlit CMOS sensor & two separate True Pic V image processors (originally developed for D-SLR cameras) to dramatically improve low-light performance, speed up camera response & enhance scene & subject recognition. Combined with high-speed sequential shooting & high-speed autofocus, i HS cuts down picture noise & enhances resolution & color gradation with fast-moving subjects, night scenes & other tricky shots.
