Panasonic LUMIX G H-X015K Leica DG Summilux 15mm f/1.7 ASPH Lens

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.

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.
