Manually focusing a lens means controlling the image result from your fingertips. A good ergonomic design makes all the difference. Carl Zeiss SLR 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 range of T* Carl Zeiss 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
State-of-the-art camera techniques and high-resolution digital image sensors increasingly demand more from the lenses. The modern floating element design compensates aberrations of the Carl Zeiss SLR lenses at different distance settings. This is accomplished by changing the axial distance of single lens elements or element groups to each other. The adjustment of the element distance is coupled to the distance setting so that it always results in the right correction. The mechanical design of these lens elements is very complex and the workmanship must be particularly exact ? both specialties of Carl Zeiss.
Virtually distortion-free optics
Dramatic perspectives and a view from extraordinary image angles ? SLR lenses from Carl Zeiss 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.
