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. Ultra-wide zoom for Micro Four Thirds mirrorless cameras provides a 14-28mm equivalent focal length range. Constant f/4 maximum aperture delivers consistent performance and illumination throughout the zoom range. Four extra-low dispersion elements help reduce chromatic aberrations and color fringing in order to achieve high clarity and color accuracy. Additionally, a pair of aspherical elements are featured in the optical design to control spherical aberrations and distortion for notable sharpness. Individual elements have been multi-coated to effectively reduce lens flare and ghosting for improved contrast when working in strong lighting conditions. Autofocus motor supports camera's contrast detection for precise focusing performance. AF can also be manually overridden for more fine-tuned control. Built-in petal-shaped lens hood shields the front element from stray light and helps reduce flare.
