Spanning a convenient 70-200mm equivalent focal length range, the Lumix GX Vario 35-100mm f/2.8 II POWER OIS Lens from Panasonic is a telephoto zoom designed for Micro Four Thirds mirrorless cameras. Working in conjunction with the versatile portrait-length to telephoto focal length range is a constant f/2.8 maximum aperture that benefits working in a variety of lighting conditions as well as affords notable control over depth of field. A pair of extra-low dispersion elements and one Ultra extra-low dispersion element are featured within the optical design, to reduce fringing and chromatic aberrations, and a Nano Surface Coating has also been applied to suppress ghosting and flare for improved contrast and color fidelity. Complementing the advanced optical design, this lens also features a POWER Optical Image Stabilizer, which is compatible with Dual IS, and a linear autofocus motor that offers quick, quiet, and near-silent focusing performance to suit video and stills applications. Additionally, this 35-100mm lens also sports a dust, splash, and freezeproof physical design to enable working in trying environmental conditions.
