Three new lenses, and an accessory lens, have been added to the Leica medium-format S line.
The Leica TS-APO-Elmar-S 120 mm f/5.6 ASPH is the first fully-adjustable tilt/shift lens for the Leica S system. This apochromatically corrected lens provides options for parallel shifting and tilting according to Scheimpflug and offers photographers the full range of adjustment options traditionally found in field cameras.
Consisting of six individual lens elements, the lens’ optical system allows parallel shifts (shift) of up to 12 mm in all directions as well as tilting of the plane of focus (tilt) by up to 8°.
Shifting and tilting movements are controlled by a total of four rings and two additional rings manually control the aperture and distance settings.
The Leica TS-APO-Elmar-S 120 mm f/5.6 ASPH will be available in January.
The first zoom lens for the Leica S system is the Leica Vario-Elmar-S 30-90 mm f/3.5-5.6 ASPH. The range is equivalent to 24-72 mm in the 35 mm format.
The lens weighs 1,345 g / 3 lbs. (with lens hood).
The lens construction is based on 14 lenses assembled in four groups. For a zoom construction, says Leica, the lens achieves extraordinarily high contrast rendition and maximum resolution wide open thanks to the use of nine lenses manufactured from glasses with anomalous partial dispersion, three of which are fluoride lenses with particularly low dispersion. Two aspherical surfaces on the rearmost lens element and one on the front lens of the second group reduce monochromatic aberrations to a minimum and ensure that imaging performance constantly remains high at close focusing distances.
The lens is fully sealed against dust and spray.
The Leica Vario-Elmar-S 30-90 mm f/3.5-5.6 ASPH will be available in November.
The Leica Super-Elmar-S 24 mm f/3.5 ASPH corresponding to a focal length of 19 mm in terms of 35 mm photography and is said to show very high contrast rendition and maximum resolution at the highest aperture.
As the result of the unusually complex construction of its focusing system, the lens offers superior imaging performance from the point of closest focus to infinity throughout the entire focusing range, says leica. During focusing, only the middle group of three lenses is moved. Concurrently, one of the lenses is moved independently as a floating element and guarantees optimum ray paths at every setting.
With an optical system comprising 12 lenses in ten groups, Leica says its optical design engineers have achieved extraordinarily high freedom from distortion for such a wide-angle lens. Five of the lenses are manufactured from glasses with anomalous partial dispersion to prevent negative effects, such as chromatic aberration. Two aspherical lenses located behind the iris and the aspherical surface of the front lens minimize monochromatic aberrations.
The Leica Super-Elmar S 24 mm f/3.5 ASPH will be available in November.
The Leica Elpro-S 180 close-up lens is a specially calculated accessory lens for the Leica APO-Elmar-S 180 mm f/3.5, reducing the close focusing distance to 1.1 meters (approx. 43 inches). Attaching this accessory lens achieves about a 30 percent increase of the reproduction ratio of up to 1:4.5.
This new release is claimed to avoid lateral chromatic aberrations.
The Leica Elpro-S 180 close-up lens accessory will be available in October.
