The Panasonic 12-35mm f/2.8 X OIS is a fast-aperture standard-range zoom lens designed for Micro 4/3 cameras and is the predecessor to the Panasonic 12-35mm f/2.8 X Power OIS II. Key features include:

Fast-Aperture Standard Zoom. With a 35mm-equivalent focal length of 24-70mm, this is the standard go-to lens that the Micro 4/3rds format has been missing.

Power OIS & Inner Focusing. It features Panasonic’s Power OIS in-lens image stabilizer, which offers twice the amount of correction as Panasonic’s previous stabilizer. Its nearly-silent autofocusing motor works great with both photo and video shooting.

Optics & Build. The optics feature Nano Surface Coating to reduce ghosting and flare, ultra extra-low dispersion glass to minimize chromatic aberration, and ultra-high refractive glass to give strong corner-to-corner performance. The Panasonic 12-35mm also features a dust- and splash-proof design, as well as a strong metal lens mount.
