The advanced design of the Leica DG Vario-Summilux 10-25mm f/1.7 delivers images with very high resolution and contrast, from corner to corner. Three aspherical elements (ASPH) as well as an Ultra-high Refractive Index element (UHR) reduce the size and weight of the lens, effectively counteract image errors such as spherical aberration and distortion and ensure maximum sharpness at all apertures. Four elements made of ED glass (Extra-low Dispersion) corrects for chromatic aberration, colour bleeding in image areas with sharp transitions in brightness.  Rugged Design – more creative options Brave the elements in nearly any kind of weather or shooting location. This lens is weatherproof and designed for use at temperatures as low as -10 °C that is tough enough to withstand even heavy field use. It protects the lens system inside from sand, rain and more, making it perfect for shooting under harsh conditions. Now there is nothing holding you back from capturing the creative nature or landscape shots you want.  Video Support – perfect video-recording With video support any user has everything they need for recording with their Lumix camera. Not only does it perform smooth aperture changes so there are no sudden jumps in exposure, it also boasts a silent design for enhanced capture of the scene’s audio. What’s more, the stunning AF performance of this lens records excellent 4K video, where precise focusing is essential.
