The new Leica DG Vario-Summilux F1.7 / 10-25mm ASPH. fully exploits the potential of the Micro Four Thirds standard by allowing large wide-angle shots despite high light intensity while remaining unusually compact. It offers exceptional imaging performance across the 20-50mm (35mm KB) zoom range and is suitable for a wide range of daily shooting situations, from dynamic landscapes to portraits. The Leica lens, with its consistently high F1.7 light intensity, enables a high aperture and effortless low-light shots, as well as a fantastic bokeh with nine aperture blades.

The lens system consists of 17 elements in 12 groups and features three aspherical lenses and four ED (Extra Low Dispersion) lenses that effectively suppress axial chromatic aberration and chromatic magnification aberration. The use of aspherical lenses and the optimal design of the lens system result in a compact size and low weight with excellent optical performance. The new lens is also especially recommended for video recording. It is compatible with the high-speed precision contrast AF system of the current LUMIX G cameras with a data exchange rate of up to 240 fps. The Leica DG Vario-Summilux F1.7 / 10-25mm ASPH. is equipped with a click-free aperture ring that allows direct, uniform control of the aperture.

The lens also features a focus clutch mechanism that allows the focus ring to be adjusted between two positions, once with and once without focus distance information. This enables fast AF/MF changes and ensures intuitive operation. The Leica DG Vario-Summilux F1.7 / 10-25mm ASPH. also excels in video recordings because it effectively reduces the effect of focus breathing. Thanks to its robust, dustproof, and splashproof design, the lens can also be used in harsh weather conditions down to 10 degrees.
