A versatile wide-angle zoom for Micro Four Thirds mirrorless cameras, the M.ZUIKO Digital ED 7-14mm f/2.8 PRO Lens from Olympus is a 14-28mm equivalent lens featuring a constant f/2.8 maximum aperture for consistent performance throughout the zoom range. Various aspherical, extra-low dispersion, and high-refractive index elements are incorporated within the design, and help to minimise chromatic aberrations and distortions for increased clarity and sharpness. Additionally, a ZERO coating has been applied to elements to control flare and ghosting for improved contrast and colour fidelity. A weather-resistant design benefits handling in trying conditions while an L-Fn button offers lens-based control over various settings. As a fast, high-performance wide-angle zoom, this Micro Four Thirds lens pairs an optimised optical layout with refined physical details to excel in a variety of working conditions.
