Today Carl Zeiss officially introduced their “Infinitely Wide” 15mm f/2.8 Distagon T* 2.8/15. in their own word “Infinitely wide horizons, cramped interiors or small objects in large surroundings – with the Distagon T* 2.8/15, all photographers can deliberately orchestrate extreme perspectives. With a field angle of 110°, the super wide angle is the ideal companion when it comes to capturing events in a way that makes them dynamic and extraordinary. Whether salt crystals or drops of water – its integrated lens shade and standard filter thread afford the front lens optimal protection from wind and weather.”
The lens incorporates a aspherical lens design to ensures consistent imaging performance throughout the entire focusing range including superior sharpness to the periphery of the image. The aspherical design sphere’s can reduce or eliminate spherical aberration and also reduce other optical aberrations compared to a simple lens.
Floating Elements Design
This lens also has 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.
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.
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.
Homogeneous image quality throughout the image field
ZEISS lenses are famous for their extraordinary image quality. Even with challenging subjects, perspective, color and light are optimally rendered – throughout the entire 35 mm image field. For this reason, we place great emphasis on particularly high image quality, e.g. low distortion and outstanding stray light reduction for rich colors.

OBERKOCHEN, GERMANY – March 16, 2012
Carl Zeiss brings out a new super wide angle lens in May 2012. The super wide angle Distagon T* 2,8/15 will be available with an EF (ZE) or F bayonet (ZF.2). With an extra-large angle of view of 110 degrees in combination with a fast f/2.8 aperture, the lens enables the features for dramatic perspectives and performance demanded by the most ambitious landscape and architectural photographers. With a unique ability to capture events in a natural and extraordinary manner, it is also an ideal companion for advertising, journalism and commercial photography.
Thanks to the extreme angle of view of the lens, the fore and background can be creatively emphasized in landscape and architecture photography. These applications will also benefit from the large depth-of-field, which provides a wide range of image sharpness from close-up up to infinity. With a close focus of 0.25m (10”) – combined with a wide angle view, photographers can work in tight spaces, while also allowing focus on close-up details. Distortion is extremely well controlled, producing naturally proportioned photographs which are not typical of many other super wide angle lenses. “With the Distagon T* 2,8/15, Carl Zeiss sets the standard in super wide angle photography,” says Dr. Michael Pollmann, Consumer Lenses Program Manager in the Camera Lens Division of Carl Zeiss AG. “Even at full aperture it achieves outstanding detail rendition and opens up room for extremely imaginative design.”
The Distagon T* 2,8/15 incorporates two aspheric lenses and special types of glass material with abnormal partial dispersion to provide an extraordinary correction of chromatic aberration. A floating elements design guarantees high image quality from close-focus through infinity. Like the other SLR lenses in the ZE and ZF.2 series, stray light and reflections are well controlled by the Carl Zeiss T* anti-reflective coating and the sophisticated treatment of the lens element edges with special light absorbing paint.
The robust all-metal barrel of the Distagon T* 2,8/15 is designed for decades of reliable service. A long focus rotation and buttery-smooth action is perfect for photographers who want to take control of their picture making, as well as for filmmakers looking for superior focus control. A nine blade aperture provides a nearly circular opening, producing natural looking out of focus details. The lens shade is integrated into the design and helps to protect the lens surface from unintentional damage. The 95mm filter thread accepts all standard filters, including the recently released Carl Zeiss T* UV and POL filters.
The lens will begin shipping in May 2012 at a recommended retail price of €2,148 or US$2,948 (excluding VAT)*.
