Precise manual focus

Manually focusing a lens means controlling the image result from your fingertips.
A good ergonomic design makes all the difference. ZEISS lenses stand out with their large rotation angle
which enables precise focusing. Changes are immediately visible in the viewfinder.
The high-quality focusing mechanism moves smoothly without play, thus also supporting the intuitive
interaction with the focal plane. The precise engraving in meter and feet, and the depth of focus scale
provide additional support for manually focusing.

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.

Virtually distortion-free optics

Dramatic perspectives and a view from extraordinary image angles – ZEISS lenses open up new composition
possibilities. Distortion would disrupt the composition because straight lines, whose image does not go through
the image center, would be reproduced with a curved shape.
This annoying effect is accordingly and largely compensated through elaborate optical designs at all focal lengths.

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.
