The Panasonic 35-100mm f/2.8 X OIS is a medium telephoto zoom lens made for Micro 4/3 cameras and camcorders and is the predecessor to the Panasonic 35-100mm f/2.8 X Power OIS II. Key features include:

Fast-Aperture Telephoto Zoom. The Panasonic 35-100mm f/2.8 X OIS offers a 35mm-equivalent focal length of 70-200mm, making it the go-to lens for sports and action shooting.

Power OIS & Inner Focusing. Between its fast f/2.8 aperture and in-lens POWER OIS image stabilizer, the 35-100mm is for great low-light performance. The nearly silent autofocusing motor makes the 35-100mm perfect for both stills and video shooting. It offers a smooth manual focus ring for manual focus pulls, and its internal focusing design means the lens won’t shift in size when focusing.

Optics & Build. The optical design utilizes two ED elements and one UED element to minimize optical aberrations, with a UHR lens delivering high resolving power and great corner-to-corner sharpness. The 35-100mm incorporates Panasonic’s Nano Surface Coating technology to minimize reflections. The lens size is quite compact—its internal zoom and focus allow it to maintain a constant 3.9-inch length. Its metal barrel gives it a solid feel, and its weather-sealed design makes it dust- and splash-proof.
