Panasonic 10-25mm f1.7 Leica DG Vario-Summilux ASPH. Lens

The full-range F1.7 aperture provides beautiful bokeh and high descriptiveness. Covering a range from moderate wide angle to standard focal length, this lens functions as a multiple fixed focal length lens providing the same, or an even higher level of descriptiveness, as a prime lens can offer. It is suitable for a variety of shooting situations, from dynamic landscapes to portraits even in low-lit scenes, dispelling the need to change lenses.

Compatibility with a high-speed sensor input to a maximum of 240-fps realises high-speed, high-precision auto focusing. Adoption of a focus clutch mechanism enables instant AF/MF switching and accurate manual focusing.

This 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 with brightness changes when zooming or panning. The optical design achieves exceptional barycentric stability to minimize image shifts during zooming. This lens also features a mechanism that suppresses focus breathing.

Comprising 17 elements in 12 groups, the lens system features three aspherical lenses and four ED (Extra-low Dispersion) lenses that effectively suppress chromatic aberration. 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 without compromising its outstanding optical performance.

The rugged dust/splash-resistant design can withstand use under harsh conditions to -10C. The metal mount endures long time use.
