The Elmarit-S 30 mm f/2.8 ASPH. 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.
