Spanning a useful range of wide-angle focal lengths, the Lumix G Vario 7-14mm f/4 ASPH. from Panasonic is a versatile wide zoom for Micro Four Thirds cameras, and offers a 14-28mm equivalent focal length. Well-suited for landscape, nature, and architectural applications, the wide field of view is complemented by a constant f/4 maximum aperture for consistent illumination throughout the zoom range. The optical design makes use of low dispersion and aspherical glass elements to control a variety of aberrations and color fringing for notable sharpness, clarity, and color accuracy, and individual elements are also multi-coated to control flare and ghosting for improved contrast. Additionally, the lens features a built-in petal-shaped lens hood to guard the front element from stray light to further reduce flaring and surface reflections.
