Thanks to its compact and high-mobility design, a constant F2.8 aperture and O.I.S. (Optical Image Stabiliser) built-in, the lens covers virtually any shooting situation. Designed to replace the outgoing LUMIX G X VARIO 12-35 mm / F2.8 II ASPH. as one of Panasonic’s highest quality LUMIX G Micro Four Thirds lenses.
