Panasonic Lumix S PRO 70-200mm f/2.8 O.I.S

Developed to be the workhorse for events, portraiture, and other mid-length subjects, the Panasonic Lumix S PRO 70-200mm f/2.8 O.I.S. is an L-mount telephoto zoom characterized by a bright f/2.8 constant maximum aperture and sophisticated optical and focusing performance. The optics layout incorporates several aspherical and low dispersion elements in order to minimize chromatic and spherical aberrations throughout the zoom range for higher clarity, sharpness, and accurate rendering. Complementing the optics is a unique double focus system, which utilizes both a linear motor and a stepping motor, to provide especially fast and precise focusing performance. A focus clutch also enables especially quick switching between AF and MF settings for fine-tuned control. Additionally, an Optical Image Stabilizer reduces the effects of camera shake for sharper handheld shooting and the lens sports a weather-sealed design for use in harsh conditions.
