High-Speed Lens

Impressive photographs captured in low light always begin with a fast lens for a system or SLR camera. Because,
a fast, high-performance lens captures as much light as possible. And a lens with a large maximum aperture leads
to the best results when shooting in unfavourable light.

Ideal aperture with nine blades

Photographers want to guide the observer through the image. Minimal depth of focus is often used as a design
element. This keeps the background intentionally blurred to keep the attention of the observer on the main subject.
These different representations of the blurred areas, as well as the quality of the transition, are referred to as
the Bokeh of a lens. The finely tuned features of the optical design on ZEISS SLR lenses ensure
a particularly harmonious effect of the blurred areas of the image.
The nine diaphragm blades and the resulting, virtually circular aperture on ZEISS SLR lenses are crucial
to favorable rendition of highlights in the fore and background.

Excellent image quality

The range of ZEISS T*® lenses offers the highest possible standards in terms of performance, reliability and, of course,
image quality. Quite simply, they are superior in every way. You can count on highly advanced flare control
for crisp and brilliant images, for example. And virtually zero geometric distortion, ensuring precise accuracy when
reproducing shapes – especially useful when photographing products and architecture.

Elaborate stray light reduction

Rich, vibrant colors are vital to creating a lasting impression. Stray light in the lens, however, would lead to a
brightening of the image, which is particularly visible in shadow areas. Image contrast is lowered; the image appears
dull and bleached. We combine various, elaborate techniques to reduce unwanted stray light.
For example, all lens elements are coated with the famous ZEISS T*® anti-reflective coating.
Additionally, a jet black special paint is applied by hand to all lens element edges to ensure that reflections
are prevented from the start.

High-quality all metal mounts

Noticeable quality and high value stability qualify ZEISS lenses for decades of intense use.
The high-quality craftsmanship of the all-metal mounts, the easy-to-grip metal focus and aperture ring and
the robust front bayonet and filter threads ensure an amazing photographic experience.
