The Olympus 7-14mm f/2.8 M.ZUIKO Digital ED PRO Lens 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 minimize 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 color 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
optimized optical layout with refined physical details to excel in a
variety of working conditions.
