LEICA DG SUMMILUX 9mm F 1.7 ASPH (H-X09)
A New Micro Four Thirds 18mm* Ultra-Wide Angle Lens with F1.7 Large Aperture

Wiesbaden, Germany, 2022/05/17 –

Panasonic is pleased to introduce a new large-aperture ultra-wide fixed focal length lens, the LEICA DG SUMMILUX 9mm F1.7 (35mm camera equivalent: 18mm) for the LUMIX G Series based on the Micro Four Thirds standard. The LEICA DG SUMMILUX 9mm (H-X09) is an unparalleled lens that features an exceptionally short focusing distance of 0.095m with an outstanding magnification ratio of 0.25x (35mm camera equivalent: 0.5x). The combination of these exceptional capabilities makes it possible to emphasize a subject’s presence in the sweeping background. It also boasts high descriptive performance and smooth, beautiful bokeh in both stills and video, clearing the stringent LEICA standards.

The LEICA DG SUMMILUX 9mm F1.7 is comprised of twelve lens elements in nine groups including two aspherical lenses, two ED (Extra-Low Dispersion) lenses and one UHR (Ultra High Refractive Index) lens to effectively suppress both axial chromatic aberration and chromatic aberration of magnification. Astigmatism is also corrected with these aspherical lenses, achieving high resolving performance. Furthermore, a UHR (Ultra-High Refractive Index) lens achieves uniform image quality from the center to edges of the image while contributing to downsizing of the lens unit. The filter diameter is 55 mm, with a 7-blade circular aperture diaphragm.

The LEICA DG SUMMILUX 9mm F1.7 is capable of smooth, silent operation to work with the camera’s AF system at max.240 fps. For the non-linear setting, focus is shifted with a variable amount according to the rotation speed of the focus ring while focus is shifted with a designated amount according to the rotational quantum of the focus ring for the linear setting. Sensitivity (the amount of focus shift per rotational quantum) can be selected from 90 to 360 degrees*¹ by 30 degrees to enable intended focus operation. The LEICA DG SUMMILUX 9mm F1.7 also excels in video recording performance with a mechanism that suppresses focus breathing, which was a fatal problem of all interchangeable lenses designed for still image photography. Together with a micro-step aperture control for smooth exposure change, professional quality video can be recorded.

With its compact size and approximately 130g light weight, the LEICA DG SUMMILUX 9mm F1.7 encompasses the stunning mobility of the Micro Four Thirds system. The rugged dust/splash-resistant*² design withstands use under harsh conditions even at minus 10 degrees Celsius for ultimate reliability.

Panasonic is committed to the development of the Micro Four Thirds lenses for the further expansion of its lineup to fulfill the needs of customers.
