Hot on the heels of the release of the Distagon T* 3.5/18 lens for the EF mount, Carl Zeiss today announced the new Distagon T* 2.8/21 ZE, a 21mm f/2.8 ultrawide lens for the Canon EOS system. Allegedly, the Distagon T* 2,8/21 ZE’s ability to flawlessly correct colour errors prevents colour fringing and unwanted lack of focus that can result from chromatic aberrations. Thanks to the Carl Zeiss T* anti-reflex coating and meticulously-crafted lenses, the Distagon T* 2.8/21 ZE is not affected by reflections or stray light either, the company claims. The Carl Zeiss Distagon T* 2.8/21 ZE will be available in autumn this year for a suggested retail price of €1,549 (including German VAT).

Zeiss Press Release

Perfect Lighting For Dramatic Perspectives

Carl Zeiss presents the Distagon T* 2,8/21 with EF Bayonet

OBERKOCHEN/Germany, 28.09.2009.
Dusk is falling in Manhattan, and a swarm of commuters on their way home is hurriedly crossing the street toward Grand Central Station. Behind them, the skyscrapers reflect the golden light of the setting sun. To capture this unique atmosphere, photographers need a fast wide-angle lens.

Carl Zeiss is proud to present the Distagon T* 2,8/21 ZE, an ultra-wide-angle lens with EF bayonet designed specifically for such tricky shooting moments. It fits all analogue and digital EOS camera models. It is ideal for archi- tectural and landscape photography. Following the recent release of the Distagon T* 3,5/18 ZE, the new Distagon T* 2,8/21 ZE is now the second Carl Zeiss wide-angle lens with EF bayonet on the market.

Photographers taking wide-angle shots often encounter image errors at the transition between bright and dark light as a result of lenses breaking the various wavelengths differently. The Distagon T* 2,8/21 ZE’s ability to flawlessly correct color errors prevents color fringing and unwanted lack of focus that can result from chromatic aberrations. Thanks to these capabilities, the Distagon T* 2,8/21 ZE is ideal for contrast-rich scenes and intense lighting angles. The lens’s floating elements design also guarantees high imaging performance, from close-ups to infinity. Thanks to the Carl Zeiss T* anti-reflex coating and meticulously-crafted lenses, the Distagon T* 2,8/21 ZE is not affected by reflections or stray light. Capturing scenes with tough lighting conditions, such as the summer dusk in downtown Manhattan, works every time—even with wide aperture settings.

The Distagon T* 2,8/21 ZE will be available in autumn this year for a suggested retail price of EUR 1.549 (including German VAT of 19%)*.
