The Panasonic 45-200mm f/4-5.6 G Vario MEGA O.I.S. Lens is an interchangeable long telephoto zoom lens, developed by Leica exclusively for Panasonic Lumix digital micro four-thirds cameras. It follows the ultra-compact Micro Four Thirds Standard, which also makes it compatible with other brands that use this same format. The focal length of this lens is equivalent to approximately 90-400mm in 35mm format terms. By incorporating the MEGA O.I.S. (Optical Image Stabilizer) feature and 3 ED elements, this lens makes it possible to capture clear, sharp images, edge to edge, even in macro shooting or low-lit situations. This provides users with a wide range of shooting flexibility.
