The Elmarit-S 30mm f/2.8 ASPH Lens from Leica illustrates what Leica optics are all about--this wide-angle lens (equivalent to 24mm in 35mm format) has a fast f/2.8 maximum aperture, which makes it a natural not only for interior, architectural and landscape photography, but for available-light photography in low-light situations. The optical design with two aspherical surfaces reduces or eliminates spherical and other optical aberrations, and delivers superior contrast and color rendition at any aperture.
This Leica lens is characterized by high resolution and extremely low distortion throughout the focusing range, which is what the Leica S System (with its very large 45 x 30mm sensor) requires. This is a lens which allows you to take full advantage of Leica's tradition of optical excellence to produce superb images.
