A Compact telephoto zoom lens for Four Thirds system.
The very latest lens coating technology and lens design reduce flare and ghosting, a common problem with digital cameras. This lens uses one aspherical lens and three Special Low Dispersion (SLD) glass elements for excellent correction of various aberrations. The rear focusing system ensures fast focusing speed as well as preventing the front of the lens rotating, making it particularly suitable for use with circular polarizing filters. A removable tripod collar is included as a standard component.
*With Four Thirds cameras, the focal length will be equivalent to 270-800mm.
