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.
