Panasonic LEICA DG SUMMILUX 9mm/F1.7 ASPH. H-X09

Introducing a new ultra-wide-angle lens with a large aperture - the LEICA DG SUMMILUX 9mm F1.7 ASPH for Micro Four Thirds cameras. This lens captures wide scenes while remaining small and portable. Its short focusing distance of 0.095m (3.7 inches) and a magnification ratio of 0.25x (35mm camera equivalent: 0.5x) allows for clear subject focus against a blurred background, making it ideal for both photography and video work.

The LEICA DG SUMMILUX 9mm F1.7 comprises 12 lens elements in nine groups, including two aspherical lenses, two ED (Extra-Low Dispersion) lenses, and one UHR (Ultra High Refractive Index) lens to suppress chromatic aberration and magnification distortion. With astigmatism correction and high resolving performance, this lens meets the stringent LEICA standards, making it suitable for professional use.

The lens operates smoothly and silently, complementing the camera's high-speed contrast AF system with sensor drive at max. 240 fps. Sensitivity can be adjusted from 90 to 360 degrees for precise focus control. The LEICA DG SUMMILUX 9mm F1.7 also excels in video recording performance with a mechanism that suppresses focus breathing and micro-step aperture control for smooth exposure changes.

Despite its impressive features, the lens remains compact and lightweight at approximately 130g (4.5 ounces), making it highly portable. Its rugged dust/splash-resistant design can withstand harsh conditions, including frigid temperatures at 10 degrees below zero. The filter diameter is 55mm, and the lens features a 7-blade circular aperture diaphragm.

In summary, the LEICA DG SUMMILUX 9mm F1.7 ASPH lens is an ideal choice for those looking to capture wide scenes with clear subject focus and excellent performance for both photography and video work. Its compact size and rugged design make it highly portable, making it a must-have for professionals and high-end amateurs.
