The DMC-ZS1 is the world's smallest digital camera with 12x optical zoom featuring 25mm ultra wide-angle f/3.3-4.9 Leica DC Vario-Elmar lens. Incorporating Panasonic's advanced optical technologies, this lens system is comprised of 10 elements in 8 groups, with 2 ED (Extra Low Dispersion) lenses and 2 aspherical lenses/3 aspherical surfaces while preserving compactness. This lens system enables a remarkable 25 to 300mm range of focal lengths in this compact body. The powerful zoom of the DMC-ZS1 can be freely controlled even when shooting motion images. Inheriting the fine rendering and outstanding quality of the Leica Elmar lens, this easy-to-carry camera delivers beautiful pictures any time, any place.The MEGA O.I.S. (Optical Image Stabilizer) in the DMC-ZS1 compensates for the blurring caused by hand-shake. It is now featured on the entire LUMIX range, and is highly popular with users around the world. Even slight hand-shake movement is accurately detected by a sampling frequency of 4,000 times per second, and compensated to produce sharp, clear images. The Venus Engine IV controls the shifting of the blur-stopping lens with even greater precision to further increase the detection accuracy and correction effect of MEGA O.I.S. (Optical Image Stabilizer). It works for zoom shots and macro shots, which are especially susceptible to hand-shake, and lets you shoot in dimly lit rooms or evening illumination to preserve the mood. In short, it lets anybody take beautiful, blur-free shots with ease.The Intelligent ISO Control function in the DMC-ZS1, made possible by the Venus Engine IV, detects subject movement and automatically adjusts the ISO setting and shutter speed to best suit the movement and light conditions. When it detects subject motion, it automatically raises the ISO setting and increases the shutter speed to prevent motion blur. On the other hand, when the subject is still and no movement is detected, it takes beautifully natural photos with a low ISO setting. Intelligent ISO Control gives you stunning images with ease because there is no need for complicated settings.The Face Detection function detects faces and automatically optimizes the focus and exposure settings. It prevents the blurry faces that happen when the camera focuses on something in front of or behind the subject, and keeps faces from appearing dark when shooting indoors or against the light source. It detects up to 15 faces at a time, making it extremely convenient for group photos. Once the camera detects a face, Face Tracking follows it even when the subject moves around. Plus, the system keeps on detection if a face turns sideways to the camera. The DMC-ZS1 is also equipped with Digital Red-eye Correction. The camera takes care of the red-eye effect that often happens when shooting with a flash, to ensure attractive facial expression always.
