The Elmarit-S 30 mm f/2.8 ASPH CS lens is equivalent, in 35 mm format, to a 24 mm super-wide-angle lens with a correspondingly expansive field of view. This, and its very fast initial aperture, makes it an ideal lens for exploring the enormous creative potentials of unusual perspectives and selective planes of focus.
When constructing super-wide lenses, immense effort must be invested to keep aberrations such as distortion or vignetting as low as possible. Five of the thirteen lenses arranged in nine groups have anomalous partial dispersion, and three of these are fluoride lenses with particularly low dispersion (colour scattering) characteristics for the correction of chromatic aberration. Two lenses are also elaborately manufactured with aspherical surfaces.
Rear-group focusing ensures consistently outstanding image performance throughout the entire focusing range and no change in the length of the lens when focusing. On top of this, its special construction provides effective protection against water droplets and dust.
Just like all other S-Lenses, the Elmarit-S 30 mm f/2.8 ASPH. is designed and constructed for maximum contrast rendition at maximum aperture, an attribute that can only be increased very slightly, and only in the extreme corners of images, by stopping down. For a lens with such a wide angle of view, its very low vignetting of only 1.5 stops and distortion of only 2.8 % (both at infinity) is negligible in practical use. Thanks to its superior imaging qualities, the creative potential offered by this super-wide-angle lens can be exploited to the full without compromise.
Broaden Your Horizons
The angle of view of the Leica Elmarit-S 30 mm f/2.8 ASPH. corresponds to that of a 24 mm lens in 35 mm format and opens up new creative horizons in image composition – in particular for indoor architectural and landscape photography. Unsurpassed excellence in colour and contrast rendition, the highest resolution and almost complete freedom from distortion guarantee perfect images at all apertures and throughout the entire focusing range. This lens is also available with a central shutter.
The optical design comprises 13 elements in nine groups. Five elements are lenses with anomalous partial dispersion. Three low-dispersion fluoride elements correct chromatic aberrations. Three elements with a particularly high refractive index and two aspherical elements minimize monochromatic aberration. During focusing, only the rear group of six elements is moved. This enables excellent imaging performance from infinity to its closest focusing distances.
