The olympus M.Zuiko ED 12-100mm f/4 IS PRO is a 24-200mm equivalent zoom
designed for Micro Four Thirds mirrorless cameras. Characterised by its f/4
constant maximum aperture, this lens offers consistent performance throughout
the zoom range to suit both stills and video shooting. Its optical design
incorporates a slew of low dispersion and aspherical elements in order to
reduce both chromatic and spherical aberrations, and both a ZERO coating and a
Z Coating Nano have been applied to greatly reduce lens flare and ghosting for
improved contrast.
