Bright, large-diameter F1.4 25mm fixed focal length lens (35mm equivalent: 50mm)

A large total of 10 lens elements in 9 groups, including a large-diameter aspherical lens, give this bright, standard F1.4 lens a superb optical performance. A large-diameter front lens ensures sufficient peripheral light levels, and a large-diameter front aspherical lens reduces light degradation all the way to the lens periphery. The result is high resolution and absolutely minimum lens distortion.

One super ED lens and three ED lenses

Four extra-low dispersion lenses suppress chromatic aberration, thus minimizing color bleeding.

Aperture ring with a familiar, intuitive touch

When the D SUMMILUX lens is used with the LUMIX DMC-L1 digital camera, the user has an aperture ring as well as a focus ring at his or her fingertips. These rings provide the same kind of easy, pleasant, intuitive operation people enjoy with the familiar film camera.

Minimum photographic distance of 38 cm for beautiful macro shooting

Unlike the 50mm lenses used on conventional 35mm film cameras, the D SUMMILUX lens uses a floating focus that reduces minimum photographic distance to just 38 cm. In addition to the lens's high optical performance and low aberration, maximum photographic magnification of 0.18x (35mm equivalent), which combines with the F1.4 brightness allows beautiful macro shooting.

Circular aperture diaphragm

Seven aperture blades create a rounded shape. This combines with the F1.4 brightness to produce a beautiful smoothness in out-of-focus areas at larger aperture.

Multiple lens coatings minimize ghosts and flare

Multi-coated lenses reduce ghosts and flare to an absolute minimum, helping the D SUMMILUX deliver an optical performance that meets Leica's lofty standards.
