Panasonic H-RSA100400 100-400mm F4.0-6.3 Micro Four Thirds Lens

The Panasonic Leica DG Vario-Elmar 100-400mm f/4-6.3 II ASPH Power OIS lens is a co-development between Panasonic and Leica Camera AG, built to meet Leica's rigorous standards for optical clarity and edge-to-edge sharpness. Offering a 200-800mm equivalent focal range on Micro Four Thirds bodies, this lens puts extraordinary telephoto reach into a form factor that remains practical for handheld shooting and field use. Its 0.5x maximum magnification at a 1.3-meter minimum focus distance bridges the gap between telephoto and macro photography, making it an exceptionally versatile tool for capturing birds, butterflies, and other small wildlife subjects without disturbing them.

Built for real-world conditions, the lens features comprehensive dust-, splash-, and freeze-resistant sealing that lets you shoot confidently in rain, snow, and temperatures down to -10°C. The autofocus system is fast and precise while remaining quiet enough for video work, with smooth aperture transitions that prevent the jarring exposure shifts that can ruin footage. Whether you are tracking a bird in flight or composing a carefully framed landscape detail from a distance, this lens delivers the optical performance and build quality that serious nature and wildlife photographers demand.
