Panasonic is pleased to introduce the second Leica interchangeable lens
designed specifically for digital SLR cameras. The LEICA D
SUMMILUX 25mm/F1.4 ASPH. complies with the Four Thirds System and will
be available by April at a suggested retail price of £749.99.
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
Bright, large-diameter F1.4 25mm fixed focal length lens (35mm
A hefty total of 10 lens elements in nine 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
One super ED lens and three ED lenses
Four extra-low dispersion lenses suppress chromatic aberration, thus
minimizing colour bleeding.
Aperture ring with a familiar, intuitive touch
When the D SUMMILUX lens is used with the LUMIX DMC-L1 digital camera,
the photographer 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 as experienced on traditional film cameras.
Minimum photographic distance of 38 cm for beautiful macro
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
0.17x (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 exacting standards.
Allowing you to choose the most appropriate lens for the given subject,
Panasonic is pleased to open the door to a unique world of creative
LEICA D SUMMILUX 25mm/F1.4 ASPH.
