Zeiss Touit 2.8/50 Makro E Lens – Sony E-Mount

ZEISS SKU: 2030-680 | Helix SKU: ZS2030680

Overview

With its exceptional image performance up to a scale of 1:1, this macro lens is the ideal choice for extreme close ups. But it also comes into its own when shooting portraits or panoramas as a light tele-lens.

The delicate structure of a petal, the tiny hairs on a cats fur or the seductive lines at the corner of the eyes whenever a shot is all about the minute details, the ZEISS Touit 2.8/50M will delight and inspire. It not only allows you to portray objects in their original size, but also provides for beautiful contrast between the pin sharp focus of the image and the softly sketched background thanks to its aperture of 2.8.

Smooth and reliable autofocus

The design of the autofocus system demands an extremely precise movement of certain lens elements. As the mass of the elements or groups to be moved within the optical system differs, various motor types may be installed. The focusing system of the Touit lenses is designed to guarantee robust and smooth autofocusing without any need for compromises or limitations in their optical design.

Information:To achieve maximum compatibility on APS-C cameras of the Sony Alpha series with E-Mount (AF in video mode) we highly recommend using the latest Sony firmware.

1:1 Macro Capability

The ZEISS Touit 2.8/50M lets you capture the smallest things and the tiniest details at their actual size. At its closest focusing distance, subjects sized 15×23 mm fill the frame with an impressive maximum reproduction ratio of 1:1. The imaging performance of the ZEISS Touit 2.8/50M is just as exceptional at such short distances as it is at medium and long distances. Minimum distortion, outstanding correction of chromatic aberrations, minimal image field curvature and excellent correction of coma and astigmatism allow true-to-life reproduction of any subject, particularly in combination with the high resolving power of modern sensors.

Full compatibility

The ZEISS Touit lenses are designed and constructed specifically for use on APS-C cameras of the Sony Alpha series with E-Mount and Fujifilm X series. The lenses are therefore fully compatible and support all camera functions, including autofocus.

Excellent resolution and high contrast

Richly saturated and vivid colours are a must in the creation of lasting impressions. However, stray light within an optical system leads to a lightening of the image that is particularly noticeable in the shadows. This reduces image contrast, with the result that exposures lack contrast and appear faded. To avoid this, ZEISS combines various specially developed technologies to reduce the undesirable effects of stray light.

Floating Elements Design

Todays 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.

Lens Design

ZEISS Touit 2.8/50M

The Planar lens design is the most successful and most frequently copied camera lens design of all time. Modifications to the tried-and-tested six-lens basic type ensure that it achieves the high imaging quality required by modern sensors. Lenses with a Planar optical design enable consistent performance across a large range of image scales the key requirement for universal macro-lenses.
