The Panasonic Leica DG Vario-Summilux 10-25mm f/1.7 ASPH. lens is a wide-to-normal zoom lens designed for Micro Four Thirds mirrorless cameras and offers an equivalent focal length range of 20 to 50mm. With a very bright f/1.7 constant maximum aperture, depth of field control and low-light shooting performance throughout the zoom range are improved. The combination of three aspherical elements, four extra-low dispersion elements, and one ultra high-refractive index element in the optical design significantly reduces colour fringing, chromatic aberrations and spherical aberrations for colour accuracy, sharpness, and high clarity. This durable 10-25mm f/1.7 ASPH. lens is splash-, dust-, and freeze-proof for working in inclement weather conditions. It features a fast 240 fps autofocus drive and an internal focusing system to deliver accurate, smooth and quiet focusing performance beneficial during both stills and video operation. Video applications are further benefitted by the de-clicked design of the physical aperture ring for a smooth and silent aperture usage. A versatile focusing clutch mechanism enables speedy switch between AF and MF, while the rounded nine-blade diaphragm contributes to a pleasant boken effect when employing selective focus techniques. A front lens cap, lens hood and lens bag are supplied for storage and transportation of your lens.
