Lumix S PRO 70-200mm f/4 O.I.S.

The Panasonic LUMIX S PRO 70-200mm f/4 O.I.S. is an L-mount telephoto zoom lens designed for full-frame mirrorless cameras, with an equivalent focal length of 105-300mm on APS-C models. The lens features a constant f/4 maximum aperture throughout its zoom range and employs advanced optical elements including one aspherical element, one ultra-high refractive index element, one ultra extra-low dispersion element, and three extra-low dispersion elements to minimize aberrations, distortion, and chromatic aberration for sharp, color-accurate imagery.

A dual focus system combining a linear motor and stepping motor delivers fast and precise autofocus performance, while the integrated Optical Image Stabilizer reduces camera shake for handheld shooting and supports Dual I.S. 2.0 functionality when paired with compatible cameras. The lens features a weather-sealed, splash and dust-resistant design rated to -14°F, a rounded nine-blade diaphragm for pleasing bokeh, and includes a removable rotating tripod collar. The optical design comprises 23 elements in 17 groups with a minimum focus distance of 3.02 feet and a 0.25x magnification ratio.
