The Panasonic Lumix S PRO 16-35mm f4 is a versatile wide-angle zoom lens designed for full-frame L-Mount mirrorless cameras. Built to Leica standards with a compact, lightweight design (500g), this lens delivers professional-grade image quality for both stills and video. The f4 constant aperture combined with advanced optical elements including aspherical, ED, and ultra-high refractive index glass ensures sharp, well-corrected imagery throughout the zoom range. Featuring fast and silent autofocus via a double-magnet linear motor system, a focus clutch for instant AF/MF switching, and weather-sealed construction with dust and splash resistance, this lens is engineered for demanding field work. The nine-blade diaphragm produces beautiful bokeh, whilst the focus breathing suppression makes it equally adept for video recording. A practical choice for landscape photographers, travel shooters, and content creators seeking optical excellence without excessive weight.
