This zoom lens has a maximum magnification of 4.2X, covering a range that extends from a wide angle of 24mm (35mm camera equivalent) - ideal for taking wide shots even indoors - to a medium telephoto focal length of 100mm (35mm camera equivalent), - optimal for portraits. A newly developed motorized zoom mechanism makes smooth, quiet zooming while shooting movies possible. The AF system is based on the MSC (Movie & Still Compatible) mechanism, and enhanced by a newly developed "Linear Motor Drive" that enables faster, quieter focusing. Macro shooting as close as 7.87 inches with a maximum image magnification of 0.72X (35mm camera equivalent) is possible. Dust and Splash Proof construction lets you shoot in harsh conditions without worry.
