The Leica DG Summilux 15mm / F1.7 ASPH. allows you to capture supreme snapshots with beautiful defocus features produced by F1.7 high speed. Certified with the name of world-renowned LEICA, the exceptional high image quality is guaranteed. The new lens system comprising of 9 elements in 7 groups uses 3 aspherical lenses. The aspherical lenses suppress spherical aberration and distortion effectively while realizing downsizing of the lens unit.
High-Precision, High-Speed AF
The inclusion of newly developed stepping motor makes the focusing action smooth and silent for use in both photo and video recording. Notably the performance of AF is by far superior to the phase-difference AF when fast lens with smaller F value is used. When mounted on the cameras of LUMIX G, you can take advantage of the high-speed, high-precision Contrast AF system.
Aperture Ring Control / Metal Finish Design
The Leica DG Summilux 15mm / F1.7 ASPH. comes equipped with aperture ring and AF/MF switch for direct, intuitive operation.
The sophisticated metal design of Leica DG Summilux 15mm / F1.7 ASPH., including the hood, deserves to bear the prestigious LEICA name. Highly reliable metal mount is durable enough for repeated exchange of lens.
Nano Surface Coating
With Panasonic's Nano Surface technology the reflection is dramatically minimized at entire visual light range (380nm-780nm) by applying the extra-low refractive index coating with nano-sized structure on the surface of the lens. It results in the super clear picture with dramatic reduction of ghost and flare.
