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. Ultra-wide zoom for Micro Four Thirds mirrorless cameras provides a 14-28mm equivalent focal length range. Four extra-low dispersion elements help reduce chromatic aberrations and color fringing in order to achieve high clarity and color accuracy. The  Autofocus motor supports the camera's contrast detection for precise focusing performance. AF can also be manually overridden for more fine-tuned control.
