A versatile, large-aperture standard lens

The LEICA DG SUMMILUX 25mm / F1.4 II ASPH. was developed as a standard reference large-aperture lens for the LUMIX G Series. It is possible to achieve a wide-angle effect, middle-telephoto effect, or telephoto effect by adjusting the combination of shooting angle, subject distance, and aperture effect. It serves as an almighty standard lens for ordinary shooting and also as a basic lens to enjoy profound photographic experiences for many years to come.

High- precision contrast AF

The LUMIX G Series is equipped with a contrast AF system and offers higher focusing accuracy than a phase-difference AF system. This lens was engineered in pursuit of the highest image rendering performance clearing LEICA’s stringent standards. The combination of the LUMIX G camera body’s high-speed, high- precision contrast AF and this lens results in exceptional shooting thanks to the lens’ excellent image rendering performance and the LUMIX G Series’ remarkable focusing performance.

*LUMIX G Series models newer than GH4 utilize a newly developed DFD (Depth From Defocus) technology to realize a faster and more accurate AF system.

Sharp and clear image rendering power

This LEICA DG SUMMILUX 25mm / F1.4 II ASPH. lens boasts superb image rendering performance in spite of its large aperture. The use of one ultra-high refractive UHR(Ultra-High Refractive Index) glass lens and two glass-molded aspherical lenses realizes uniform rendering from the center of the frame to the edges, while the Nano Surface Coating minimizes ghosts, flare and flare rate, thus boosting tonal reproduction and image clarity. Furthermore, the inner-focus system assures stable and high rendering and high-speed, silent drive across the entire range from infinity to the closest shooting distance.
