The Panasonic LUMIX G VARIO 100-300mm / F4.0-5.6 / MEGA O.I.S. is a handheld ultra-telephoto zoom with an astonishingly compact and light weight profile. Panasonic's MEGA O.I.S. (Optical Image Stabilizer) powerfully compensates for the hand shake which severely affect the zoom shots to suppress blur. This lens is comprised with 17 elements in 12 groups including an ED lens. Adopting the ED lens in the first lens group, the chromatic aberration is effectively suppressed to render sharp, high contrast images with stable optical performance over the entire zoom range.
The integration of stepping motor with exclusive zoom tracking control system and inner focus drive system realizes the use of accurate and high speed contrast AF, yet keeping its sound of action as silent as possible. Seven blades give the aperture a rounded shape that produces an attractively smooth effect in out-of-focus areas when shooting at larger aperture settings. Highly reliable metal mount assures durability for active use, and uses multi-coated lens elements that minimize ghosts and flare to further enhance its shooting performance.
