Characterized by its slim, retractable form factor, the Lumix G Vario 12-32mm f/3.5-5.6 ASPH. from Panasonic is a 24-64mm equivalent standard zoom for Micro Four Thirds mirrorless cameras. Despite its sleek stature, the lens's sophisticated optical design uses three aspherical elements and one extra-low dispersion element to correct spherical and chromatic aberrations for notable sharpness and clarity throughout the zoom range. A stepping AF motor and internal focus design are also employed for quick, quiet focusing performance that suits movie and photo applications, and MEGA O.I.S. helps to ensure sharp handheld photos by compensating for the effects of camera shake.
