The MEGA O.I.S. compensates for blurring caused by hand-shake. Apart from the digital image correction, the MEGA O.I.S. corrects a jolt of light axis by shifting the O.I.S. lens unit to offset it. Thus the image is not affected digitally nor deteriorated at all. The MEGA O.I.S. lets you shoot in dimly lit rooms or evening illumination without losing the mood. It also works for macro shots and zoom shots, which are especially susceptible to hand-shake. In the iA Mode, advanced detection functions work automatically and simultaneously to optimize your settings, making it easier than ever to take beautiful photos every time. The iA Mode includes the MEGA O.I.S. to detect hand-shake, Intelligent ISO Control to detect subject movement, Face Detection AF/AE to detect faces in the frame and adjust the brightness of the face properly, Intelligent Scene Selector to detect scene conditions, and Intelligent Exposure to detect the brightness level. The DMC-FH4 is capable of recording 14.1-megapixel high-resolution photos. The Sonic Speed AF helps to catch even the most fleeting photo opportunities. In video recording, the DMC-FH4 can record motion pictures in high-definition (1,280 x 720 pixels in Motion JPEG format). With the LUMIX Image Uploader, you can upload photos to Facebook and videos to YouTube with simple operation. The DMC-FH4 packages a 28mm wide-angle 4x optical zoom lens (35mm camera equivalent: 28-112mm) into a compact body. The 28mm wide-angle lens is convenient for shooting group portrait, subjects indoor or dynamic landscapes. The 4x optical zoom increases its power to 8x equivalent with the Intelligent Zoom function. This is an extensive zoom function using digital zoom with minimum deterioration of image quality thanks to the Intelligent Resolution technology.
