The Panasonic Leica DG Summilux 10-25mm F1.7 ASPH is a groundbreaking wide-to-standard zoom lens for Micro Four Thirds systems. With a constant f/1.7 aperture across its 20–50mm equivalent range, it’s a filmmaker’s fantasy and a photographer’s precision tool rolled into one.
Comprising 17 elements in 12 groups—including 3 aspherical, 4 ED, and 1 UHR element—this lens delivers exceptional sharpness, minimal distortion, and rich contrast. The nine-blade diaphragm ensures smooth, rounded bokeh for artistic depth and visual allure.
Designed with internal focusing and a stepless aperture ring, the lens offers fluid transitions ideal for video work. The linear manual focus system provides intuitive control, while autofocus remains fast and whisper-quiet—perfect for both cinematic and still capture.
Wrought for endurance, the lens bears a shell immune to dust, spray, and frost. Be it dripping jungles or gale-swept highlands, the H-X1025E stays steadfast and sure.
This lens allows for intimate close-ups without sacrificing clarity or depth. Ideal for capturing textures, details, and spontaneous moments.
Though substantial in size, its build quality and versatility justify every gram—especially for creators who demand excellence.
Engineered in collaboration with Leica and crafted by Panasonic, the DG Summilux 10-25mm F1.7 ASPH isn’t just a lens—it’s a portal to visual storytelling at its most evocative.
