Panasonic introduced the second Leica interchangeable lens designed specifically for the digital SLR camera. The LEICA D SUMMILUX 25mm/F1.4 ASPH. complies with the Four Thirds System.
The new LEICA D SUMMILUX 25mm/F1.4 lens (35mm equivalent: 50mm) is a bright, large-diameter F1.4 standard lens. It incorporates an aperture ring and boasts as many as 10 lens elements in 9 groups, including a large-diameter aspherical lens, which assure a superb optical performance and F1.4 brightness, while one super ED (extra-low dispersion) lens and three ED lenses reduce color bleeding to an absolute minimum.
