Product Description

The Panasonic Lumix S 18-40mm f/4.5-6.3 is an ultra-compact full-frame zoom lens notable for being one of the smallest and lightest lenses in its class—measuring just 67.9 × 40.9 mm and weighing approximately 155 g. It offers a versatile wide-to-standard focal length ideal for landscapes, street scenes, and environmental portraits. The retractable barrel design allows the lens to stay pocketable when not in use, and it extends seamlessly when zoomed. The optical formula includes eight elements in seven groups, with three aspherical elements, two extra-low dispersion (ED) elements, and one ultra-high refractive (UHR) element for sharpness and clarity across the frame. Dust-, splash-, and freeze-resistant coatings, including a fluorine coating on the front element, make it travel-ready. Autofocus is quiet and responsive, with minimal focus breathing—ideal for hybrid photo and video use.
