Spanning a versatile telephoto range, the Lumix G X Vario PZ 45-175mm f/4-5.6 ASPH. POWER O.I.S. from Panasonic is a 90-350mm equivalent lens designed 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, and a floating elements system is also used to maintain clarity throughout the zoom and focus ranges. A Nano Surface Coating has also been applied to suppress lens flare and ghosting for greater contrast when working in harsh lighting conditions.

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.
