About the Panasonic LEICA 10-25mm F1.7 – MFT
Panasonic LUMIX is proud to introduce a new standard zoom digital interchangeable lens, the LEICA DG VARIO-SUMMILUX 10-25mm / F1.7 ASPH. (H-X1025), which boasts a large F1.7 aperture throughout the entire 20-50mm (35mm camera equivalent) zoom range with exceptionally high optical performance clearing the stringent LEICA standards. The LEICA DG VARIO-SUMMILUX 10-25mm / F1.7 ASPH. is suitable not only for shooting stills but also for video to satisfy both professional photographers and videographers.

The full-range F1.7 high-speed aperture provides beautiful bokeh and outstanding image quality. Covering a focusing distance from wide angle to standard zoom range, the LEICA DG VARIO-SUMMILUX 10-25mm / F1.7 ASPH. functions as a multiple fixed focal length lens providing the same or an even higher level of image quality than prime lenses can offer. It is suitable for a variety of daily shooting situations, from dynamic landscapes to low-light , 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 will effectively suppress 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.

Compatibility with a maximum 240-fps high-speed sensor drive realizes high-speed, high-precision auto focusing. Notably, the new lens excels in video recording performance. In addition to the silent operation achieved by the inner focus drive system, the step-less 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 LEICA DG VARIO-SUMMILUX 10-25mm / F1.7 ASPH. also excels in performance with a mechanism that suppresses focus breathing, which was a problem of interchangeable lenses designed for still image photography.

The rugged dust/splash-resistant design withstands use under harsh conditions even in 10 degrees below zero for high mobility. Nine blades give the aperture a rounded shape that produces an attractively smooth defocus effect in out-of-focus areas when shooting at larger aperture settings. Filter diameter is 77mm. Highly reliable metal mount ensures long term use.
