Homogeneous image quality throughout the image field

ZEISS lenses are famous for their extraordinary image quality. Even with challenging subjects, perspective,
color and light are optimally rendered – throughout the entire 35 mm image field. For this reason, we place great
emphasis on particularly high image quality, e.g. low distortion and outstanding stray light reduction for rich colors.

Excellent image quality

The ZEISS range of 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.

Floating Elements Design

Today’s camera technologies and high-resolution sensors demand continuous improvement of lens performance.
Thanks to the use of the latest floating element design principles, optical aberration effects in ZEISS lenses are reduced
to a minimum throughout their entire focusing range. This is achieved by variation of the axial distance between
individual lens elements or groups. This adjustment of the lens-to-lens distance is coupled to the distance setting
to ensure correct compensation at all times. The mechanical construction of these lenses is extremely complex
and they must be assembled with utmost precision – both of which are key competencies of ZEISS.

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.

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.
