The Panasonic Lumix G Vario 45-150mm f/4-5.6 ASPH. MEGA O.I.S. Lens is compatible with Micro Four Thirds mirrorless cameras and provides a 90-300mm equivalent focal length range. One UHR (Ultra-High Refractive Index) element pairs with two aspherical elements to reduce chromatic aberrations and distortions for consistent edge-to-edge sharpness and illumination. Multi-coatings have also been applied to individual elements to reduce lens flare and ghosting for increased contrast and color fidelity in harsh lighting conditions.
