Carl Zeiss expands its range of SLR lenses with the addition of the Distagon T* 3,5/18 super wide angle lens.
 With an impressive field of view of 99°, this new, rectilinear lens provides dramatic perspectives for
architectural, landscape and close-range photography for photographers utilizing full-frame DSLRs or film-based  cameras. The Distagon T* 3,5/18 is a derivative of the ZEISS designs for the Contax RTS series of cameras, but utilizing all modern materials and eco-friendly glass materials.

The Distagon T* 3,5/18 is designed with a floating lens element in the rear lens assembly, which results in impressive image quality from infinity to the closest focus range. Utilizing the superior ZEISS T* anti-reflective coating and critically designed interior elements, the lens is remarkably free from stray light artifacts and internal reflections. Images are brilliantly rendered, with extremely crisp resolution right to the edges – even at wide-open apertures under the most difficult lighting conditions. Like all Carl Zeiss SLR lenses, the Distagon T* 3,5/18 uses the ZEISS ‘color matching technology’, which provides homogeneous color rendition across all focal lengths in the product range.
