The optical design, with internal focusing, has 13 lens elements in 10 groups, one with an aspherical surface. This super-wideangle lens has virtually no flare, it is not sensitive to reflections and delivers first-class images at full aperture. Contrast and sharpness are extremely high, so that the finest details are resolved into the very corners of the image. The Super-Elmarit-R has a built-in filter revolver with a neutral density filter, a KB12 artificial light conversion filter, a yellow-green filter and an orange filter. Its very wide angle of view and its impressive rendition of perspectives are superbly suitable for landscape and architectural photography, as well as for covering the full scene in confined interior quarters. Dynamic perspectives with dominant foregrounds are made possible by the large angle of view and the short near focusing distance of only 18 cm (7 in).
