100–300mm · f/4–5.6
The Panasonic Lumix G Vario 100-300mm F4-5.6 OIS is a consumer-grade super-telephoto zoom for Micro Four Thirds, offering a 200-600mm equivalent reach. Optically, it delivers excellent center sharpness at 100mm and good performance across the frame when stopped down, but at 300mm it becomes softer, especially wide open. Weaknesses include slow autofocus in low light and a tendency to hunt. Build quality is mostly plastic with a metal mount, but it lacks a tripod collar. The OIS provides 3-4 stops of stabilization, though a monopod is still recommended for consistent sharpness. It suits budget-conscious wildlife and sports shooters who need reach without investing in pricier alternatives.
