Panasonic is introducing a new standard zoom digital interchangeable lens, the LEICA DG VARIO-SUMMILUX 10-25 mm/F1.7 ASPH. (HX1025). The lens boasts a large F1.7 aperture throughout the entire 20-50 mm (35 mm camera equivalent) zoom range with exceptionally high optical performance clearing the stringent LEICA standards. The LEICA DG VARIO-SUMMILUX 10-25 mm/F1.7 ASPH. is suitable for photo shooting and video recording to satisfy both professional photographers and videographers.The full-range F1.7 high-speed aperture provides beautiful bokeh and high descriptiveness. Covering a focusing distance from wide angle to standard zoom range, the LEICA DG VARIO-SUMMILUX 10-25 mm/F1.7 ASPH. functions as a multiple fixed focal length lens providing the same or an even higher level of descriptiveness than a fixed focal length lens. It is suitable for a variety of daily shooting situations, from dynamic landscapes to portraits even in low-lit scenes, dispelling the need to change lenses depending on the situation.Comprising 17 elements in 12 groups, the lens system features three aspherical lenses and four ED (Extra-low Dispersion) lenses that effectively suppress the axial chromatic aberration and chromatic aberration of magnification. Spherical aberration and distortion are also corrected by the aspherical lenses for stunning high resolution. The use of aspherical lenses and the optimum design of the lens system results in a compact size and light weight despite its outstanding optical performance.
