Features

Smooth and Reliable Autofocus

The autofocus system of the ZEISS Touit lenses is designed for extremely precise movement of certain lens elements. Different motor types may be used depending on the mass of the elements or groups being moved within the optical system. The focusing system is designed to provide robust and smooth autofocus without compromising the optical design.

Full Compatibility

The ZEISS Touit lenses are specifically designed for APS-C cameras in the Sony Alpha series with E-Mount. The lenses are fully compatible and support all camera functions, including autofocus.

Virtually Distortion-Free Optics

ZEISS lenses provide dramatic perspectives and extraordinary image angles while largely compensating for distortion through elaborate optical designs. This helps prevent straight lines away from the image center from appearing curved and supports different composition possibilities.

ZEISS T* Coating

The optical elements of ZEISS lenses feature T* anti-reflective coating on all surfaces. This coating and the optical design are intended to provide images with superior brilliance, including in unfavourable lighting conditions. The coating is applied to the lens surfaces through the deposition of extremely thin, transparent layers on the glass to reduce reflective properties.

Floating Elements Design

Modern camera technologies and high-resolution sensors demand continuous improvement in lens performance. The floating element design used in ZEISS lenses helps reduce optical aberrations throughout the focusing range. This is achieved by varying the axial distance between individual lens elements or groups according to the distance setting, providing compensation across the focusing range.
