The MEGA O.I.S. compensates for blurring caused by h&-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 & zoom shots, which are especially susceptible to h&-shake.
