Notes & Features: Optical Image Stabilization (OIS); Motion Detection technology consolidates motion information for both the camera and the photographic subject and determines whether the subject has moved and what if any adjustments to focus or exposure needs to be made; Hi-ISO Auto function that works together with Motion Detection Technology to reduces the effect of blur in low light shooting situations by automatically changing and balancing the ISO sensitivity along with the shutter speed. Waterproof to 33ft/10m; Crushproof to 220lbf/100kgf; Shockproof to 7ft/2.1m; Freezeproof to 14°F/-10°C; Dustproof. Available in black, silver or white.
