Panasonic 9mm / F1.7 ASPH. LEICA DG SUMMILUX

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 (HX09) is not only an ultra wide-angle lens with a large aperture, but also an unparalleled lens.  It 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 project the subject’s presence in the sweeping background. It also boasts high descriptive performance and smooth, beautiful bokeh, clearing the stringent LEICA standards. It’s suitable for professional and amateur users for both photo and video.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 resolution 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 the lens unit.The LEICA DG SUMMILUX 9mm F1.7 is capable of smooth, silent operation to work with the camera’s high-speed, high-precision contrast AF system with the sensor drive at max. 240 fps. For the non-linear setting, focus is shifted with a variable amount. This is due 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 degree increments 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 approximately 130g compact size and light weight, the LEICA DG SUMMILUX 9mm F1.7 features stunning mobility that the Micro Four Thirds system boasts. The rugged dust/splash-resistant*2 design withstands use under harsh conditions even at 10 degrees below zero. The filter diameter is 55mm, with a 7-blade circular aperture diaphragm.
