Delivery of the LEICA SUMMARIT-S 35 mm f/2.5 ASPH. begins
With the LEICA SUMMARIT-S 35 mm f/2.5 ASPH. Leica expands their range of lenses for the Leica S2 professional camera with another significant focal length. Following the LEICA SUMMARIT-S 70 mm f/ 2.5 ASPH. and the LEICA APO ELMAR-S 180 mm f/ 3.5 lenses, the Summarit-S 35 mm f/2.5 ASPH. is now the first fast wide-angle lens of the Leica S-System. The lens is now available from selected specialised camera dealers.
The focal length of the LEICA SUMMARIT-S 35 mm f/2.5 ASPH. provides an angle of view equivalent to that of a 28 mm lens for 35 mm photography (crop factor 0.8). With a maximum aperture of 1:2.5, it offers a significantly higher speed than other lenses available in the medium format segment and provides superior imaging qualities at all apertures from its closest focus setting to infinity. The LEICA SUMMARIT-S 35 mm f/2.5 ASPH. therefore satisfies not only the needs of landscape and architectural photographers but is also ideal for use in the studio or out on reportage assignments. The extreme maximum aperture of the lens enables photographers to use selective focus and is particularly effective for creative photography.
Absolute dedication to superior imaging quality is a key factor in the design and construction of all Leica S lenses. This is, for instance, the reason for the use of specially formulated glasses in their construction. At the same time, extremely narrow tolerances in the manufacturing process guarantee the superior performance of all S-System lenses. Vignetting and aberrations, such as distortion and chromatic aberration, are reduced to a hardly detectable minimum.
This naturally also applies to the LEICA SUMMARIT-S 35 mm f/2.5 ASPH.: its sophisticated construction with eleven elements in nine groups (incorporating two aspherical lens surfaces and five special glasses with anomalous partial dispersion) and rear group focusing ensure consistently high imaging quality from infinity to its minimum focusing distance of 55 centimetres. The LEICA SUMMARIT-S 35 mm f/2.5 ASPH already reveals its outstanding performance at maximum aperture: outstanding contrast in even the finest structures and excellent reproduction of details across the entire image field.
As with all Leica S-System products, the design of the LEICA SUMMARIT-S 35 mm f/2.5 ASPH. is tough and built to last a lifetime. The lens is equipped with a robust bayonet mount and is elaborately protected against dust and water spray. This ensures absolute reliability even under the harshest conditions.
