The second-generation LUMIX G 100–300mm is a Micro Four Thirds telephoto zoom for subjects that cannot easily be approached. Its 200–600mm-equivalent field of view is useful for birds, distant animals and outdoor action. POWER O.I.S. helps with camera shake, while the variable zoom makes it easier to find a subject before tightening the frame. Choose it for a dedicated long-reach role alongside a standard lens. The narrow view magnifies framing errors as well as distant detail, so a stable shooting position and appropriate shutter speed matter. The F4–5.6 aperture is more comfortable in good light than in dark venues. Verify the H-FSA100300 model number to distinguish this version from the earlier 100–300mm lens.
