The Panasonic Leica DG Vario-Summilux 10-25mm f/1.7 is a wide-to-normal zoom lens for Micro Four Thirds mirrorless cameras. It offers a 20-50mm (35mm equivalent) focal length and an aperture range of f/1.7 to f/16. The lens employs three aspherical elements, which help minimize distortion and spherical aberrations for sharp, clear imagery. For precise focusing, the lens has a fast 240 fps autofocus drive with inner focusing and a stepping motor for completely silent operation.
A splash, dust, and freeze-proof design helps ensure that this lens is ready for use in harsh conditions. A rounded nine-blade diaphragm ensures smooth bokeh when shooting at wide apertures.
