Panasonic Leica DG Vario-Summilux 10-25mm f/1.7 Lens - H-X1025
LEICA DG VARIO-SUMMILUX 10-25mm / F1.7 ASPH. H-X1025 from Panasonic is built for mirrorless Micro Four Thirds mount cameras and enables F1.7 aperture brightness throughout the entire 20-50mm (35mm camera equivalent) zoom range with exceptionally high optical performance clearing the stringent LEICA standards. Suitable not only for photo shooting but also for video recording to satisfy both professional photographers and videographers.
LEICA DG VARIO-SUMMILUX
LEICA Camera AG’s strict quality standards optimized for photo/video has been developed into this ruggedized mirrorless Micro Four Thirds mount lens.
F1.7 Full Range
F.17 high-speed aperture brightness is available across the entire zoom range of 10-25mm (35mm camera equivalent of 20-50mm).
Lens System
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 stunningly 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.
Performance
Compatibility with a maximum 240-fps high-speed sensor drive realizes high-speed, high-precision autofocusing. Notably, the new lens excels in video recording performance. In addition to the silent operation achieved by the inner focus drive system, the stepless “de-clicked” aperture ring and micro-step drive system in the aperture control section help the camera to smoothly catch up to brightness changes when zooming or panning. The optical design achieves exceptional barycentric stability to minimize image shifts during zooming. Adoption of a focus clutch mechanism enables instant AF/MF switching and accurate manual focusing. The lens 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.

Translated press release:
Panasonic has introduced a new standard digital zoom lens, LEICA DG VARIO-SUMMILUX 10-25mm / F1.7 ASPH. (H-X1025) with a wide aperture of F1.7 over the entire zoom range of 20-50mm (35mm camera equivalent) with exceptional optical performance that meets the strict LEICA standards.
LEICA DG VARIO-SUMMILUX 10-25mm / F1.7 ASPH. is an appropriate objective not only for still pictures but also for video recordings to meet professional photographers and videographers at the same time.
The full-range F1.7 high-speed aperture guarantees a stylish bokeh and a high descriptive degree. Covering a wide-angle focus range at the standard zoom range, the LEICA DG VARIO-SUMMILUX 10-25mm / F1.7 ASPH provides more flexibility than multiple fixed focal lenses covering the same focal length. It is suitable for a variety of day-to-day shooting situations, from dynamic landscapes to portraits even in low-light scenes, thus eliminating the need for objectives according to the situation.
Comprising 17 elements in 12 groups, the lens system includes three aspheric lenses and four ED lenses that effectively suppress axial chromatic aberration and chromatic aberration in case of magnification. Spherical aberration and distortion are also corrected with aspheric lenses for an absolutely stunning high resolution. The use of aspherical lenses and the optimal design of the lens system ensure compact dimensions and low weight, despite exceptional optical performance.
The new lens is compatible with the 240fps communication system with the new Panasonic cameras, providing high-precision high-precision auto-focus. In addition, the new goal excels in the performance of video footage. Besides silent operation, the aperture control ring helps the camera to regain adaptive brightness changes in the case of zoom or panning. Optical design guarantees exceptional barcidity stability to minimize image zooming. Adopting a focus coupling mechanism allows instant AF / MF switching for precise manual focus. LEICA DG VARIO-SUMMILUX 10-25mm / F1.7 ASPH. also excels in video recording performance, with a mechanism that suppresses any potential imbalance in focus,
Robust, dustproof / splash-proof * design guarantees hard use even at temperatures of -10 degrees for a high degree of mobility. The nine blades give the apertures a round shape that produces an appealing defocusing effect in defocused areas, wide-apertured photos. The diameter of the filter is 77mm. The durable metal mounting ensures a long service life.
Panasonic is committed to expanding the Micro Four Thirds range with LUMIX G series cameras and lenses.
