Description — Panasonic 100-400mm f/4-6.3 II ASPH.
The Panasonic Leica DG Vario-Elmar 100-400mm f/4-6.3 II ASPH. is a super telephoto zoom lens designed exclusively for the Micro Four Thirds mirrorless system. Its focal length range spans 100mm to 400mm, providing extensive reach for subjects at a distance. The variable maximum aperture runs from f/4 at the wide end to f/6.3 at full telephoto extension.
Built-in optical image stabilization works to counteract camera shake that becomes more apparent at longer focal lengths. The lens accommodates both autofocus and manual focus, offering shooters the ability to adapt their approach based on the demands of the scene. A 72mm filter thread makes it straightforward to attach commonly available filters.
Tipping the scales at 985g, the lens carries a meaningful but manageable weight for a zoom of this reach. The Micro Four Thirds mount ensures native compatibility across the MFT mirrorless camera lineup, making this lens a strong option for photographers looking to extend their telephoto capabilities within the MFT system.
