The LUMIX S PRO 70-200mm F2. 8 O. I. S. (S-E70200) is a large-aperture telephoto zoom lens that boasts high descriptive performance across the entire zoom range. It is designed and developed for professional field photography. Astigmatism is corrected with an aspherical lens, achieving high resolving performance. Covering from 70mm to 200mm by itself, the use of a LUMIX Teleconverter allows maximum 280mm (1. 4x, with DMW-STC14) and 400mm (2x, with DMW-STC20) super telephoto shooting, with maximum 480 fps focus control for high-speed, high-precision auto focus. The O. I. S. (Optical Image Stabilizer) in the lens complies with LUMIX camera Body I. S. and the 5-Axis Dual I. S. 2 makes it possible to use a 7-stop slower shutter speed. Adoption of a focus clutch mechanism enables instant AF/MF switching and accurate manual focusing. * Dust and Splash Resistant does not that damage will not occur if this lens is subjected to direct contact with dust and water.
