The Panasonic LUMIX G X Vario 45-175mm f/4.0-5.6 is a compact and lightweight 90-350mm equivalent zoom for Micro Four Thirds mirrorless cameras. The lens’s optical design includes a pair of aspherical elements and a pair of extra-low dispersion elements, which help to control aberrations, distortion, and color fringing in order to realize a sharp, color-accurate image quality
Complementing the imaging capabilities, this lens is also characterized by its power zoom design that affords smooth, controllable zoom adjustment via a built-in switch. POWER O.I.S. also helps to minimize the appearance of camera shake for sharper handheld shooting and a stepping AF motor, along with internal focusing design, contributes to quick, quiet focus performance to suit both photo and video applications.
