Distortion-free. Snapshots for well-proportioned reproduction

It’s no easy matter to get a fresh photographic take on familiar locations, particularly because photographers often try to imitate the images that are familiar to them from picture postcards, posters, and photography books.

And in addition to this artistic challenge, there’s also the technical one – because even the optimum angle won’t produce a satisfactory result if the camera distorts the scene. Distortion-free pictures are particularly important for architectural photographs.

However, many of the zoom lenses people use on holiday and on city tours do not meet these requirements. In telephoto shots, uncorrected lenses tend to distort the edges of the image (billowing) and wide-angle shots have barrel-shaped artefacts. This can result in distortion – sometimes beyond recognition – of even the most magnificent building or monument. Thanks to intelligent combinations of aspheric and spherical lens elements, Schneider-Kreuznach lenses counteract unavoidable distortions for both short and long focal lengths using extensive correction. The lenses are designed and built in such a way that straight lines in particular are rendered as such.

Schneider-Kreuznach lenses counteract another problem through the use of low-dispersion ED glass. Particularly in urban and architectural photography, images often include angular structures, such as the walls of buildings, gables and windows. The light-to-dark and dark-to-light transitions at the sharp contours of such elements can cause colour fringes (chromatic aberrations) in pictures taken using unsophisticated lenses. This problem is largely eliminated through the use of anti-dispersion ED glass.
