A perfectionist with an eye for the details

Touit 2.8/50M

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.

ZEISS Touit 2.8/50M

A perfectionist with an eye for the details

The delicate structure of a petal, the tiny hairs on a cat’s 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.

Planar Design

Touit 2.8/50M

The famous symmetric lens design invented by Dr. Paul Rudolph at ZEISS in 1896. The Planar lens is the most successful camera lens design – and, by the way, the most plagiarized – ever created. It provides the lens designer with numerous means to correct aberrations extraordinarily well. And its performance is very constant over a wide range of imaging ratios, enabling such a versatile lens variety as the Makro-Planar lens.

Makro Planar with 14 lens elements in 11 groups
Lens with aspheric optical surface
Lens made of special glass with anomalous partial dispersion
"Floating Elements" design

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 reach the best compatibility on Sony NEX Cameras (AF in video mode) we highly recommend to use the latest Sony NEX firmware.

1:1 macro capability

The 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 15x23 mm fill the frame with an impressive maximum reproduction ratio of 1:1. The imaging performance of the 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 Sony NEX and FUJIFILM X Series cameras with APS-C sensors. The lenses are therefore fully-compatible and support all camera functions, including autofocus.


Excellent resolution and high contrast

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.

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 characteristics

Photographers want to lead the viewer through their images. Planes with minimum depth of focus are often employed as creative elements. For instance, the background is kept intentionally out of focus to lead the viewer’s eye to the actual subject of the image. The Touit lenses feature a nine-blade iris that closes to create an almost perfectly circular aperture. The effect of this is the creation of a particularly harmonious effect in the out of focus areas of the image (‘Bokeh’).
