Spanning a convenient 70-200mm equivalent focal length range, the redesigned Leica DG Vario-Elmarit 35-100mm f/2.8 POWER O.I.S. Lens from Panasonic is a telephoto zoom designed according to Leica's strict quality standards 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 an anti-reflective coating inside the lens barrel has been added to the original Nano Surface Coating that has also been applied to suppress ghosting and flare even under strong light sources. Complementing the advanced optical design, this lens also features a POWER Optical Image Stabilizer, which is compatible with Dual I.S., 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.
