A fast, normal prime designed for Micro Four Thirds mirrorless cameras, the Lumix G 25mm f/1.7 ASPH. from Panasonic is a 50mm equivalent lens featuring a bright f/1.7 maximum aperture for enhanced low-light shooting and depth of field control. One UHR (Ultra-High Refractive Index) element pairs with two aspherical elements to reduce spherical aberrations and distortions for consistent edge-to-edge sharpness and illumination. A Nano Surface Coating has been applied, too, and helps to reduce flare and ghosting for increased contrast and color fidelity. The optical construction also helps to realize a compact overall form factor, measuring just 2"-long and weighing 4.4 oz. Benefitting both stills and video capture, this lens also incorporates a stepping motor for smooth, quiet autofocus performance that is compatible with Lumix cameras' high-speed contrast-detection focusing systems.
