LEICA DG SUMMILUX 25mm / F1.4 SUMMILUX 25mm.
Micro Four Thirds 25mm Single Focal Length Lens / 50mm (35mm camera equiv.)
A Superb Image Quality with Minimum Distortion, Chromatic Aberrations That Passes a Stringent Leica Standard
The LEICA DG SUMMILUX 25mm / F1.4 ASPH. (35 mm camera equivalent: 50mm), based on the Micro Four Thirds System standard, features outstanding brightness of F1.4 realized in the compact and light weight profile. The extraordinary brightness allows a beautiful soft focus for photo and video to be even more impressive and encourages users not to use the flash even in dimly-lit conditions. Certified with the name of world-renowned LEICA, the exceptional high image quality is guaranteed.
UHR Index Lens and Glass Mold Aspherical Lenses for Achieving Uniformed Description from the Center to the Edges
The lens system comprising of nine elements in seven groups uses two aspherical lenses and one UHR (Ultra High Refractive) index lens. The newly developed UHR index lens and glass mold aspherical lenses achieve uniformed description from the center to the edges.
Contrast AF System Support, Circular Aperture Diaphragm and Durable Metal Mount
When mounted on the LUMIX G Micro System cameras, this lens can take maximum advantage of contrast AF system, which boasts both high accuracy and high speed for more stress-free shooting. Notably the performance of AF is by far superior to the phase-difference AF when fast lens with smaller F value is used.
Seven blades give the aperture a rounded shape that produces an attractively smooth effect in out-of-focus areas when shooting at larger aperture settings. Highly reliable metal mount is durable enough for repeated exchange of lens.
