There’s a rumor going around that Zeiss will be announcing a new Distagon T* 2,8/15 ZF.2/ZE super wide angle lens on March 16, 2012. This new lens will have an angle of view of 110 degrees and a 95mm filter thread.
As it stands currently, the widest Zeiss lens currently available is the Distagon T* 18mm f/3.5, which retails for $1,395. The lens is equipped with internal lens groups that are repositioned during focusing with a floating elements design, allowing it to deliver exceptionally high quality shots. These lenses also have a more compact design compared to other zoom lenses that belong in its category, for increased portability.
Zeiss also manufactures the Super Wide Angle 15mm f/2.8 Distagon T* ZM lens for M-mount that’s priced at a hefty $4,600. These lens feature high resolving power at wide apertures that allows interior photography without the use of a tripod possible. It also allows photographers to capture images with exceptional composition, even in tight spaces for extremely dynamic architectural photos.
The rumor goes on to state that the new Distagon T* 2,8/15 will be made available for Canon and Nikon mounts.
