Spanning a versatile focal length range while retaining a compact form factor, the Lumix G X Vario PZ 14-42mm f/3.5-5.6 ASPH. POWER O.I.S. from Panasonic is a slim 28-84mm equivalent zoom for Micro Four Thirds mirrorless cameras. Contributing to its sleek profile, the optical design uses four aspherical elements to also reduce spherical aberrations and distortion throughout the zoom range. A pair of extra-low dispersion elements are also featured, to control chromatic aberrations and color fringing, and a Nano Surface Coating has been applied to suppress flare and ghosting. Additionally, the lens uses a stepping AF motor and internal focus design for quick and quiet focusing performance and POWER O.I.S. helps to compensate for the effects of camera shake in order to deliver sharper imagery when shooting handheld.
