On June25, 2008 without too much fanfare, Carl Zeiss Company announced yet another lens for the Nikon (ZF) and Pentax (ZK) DSLR mounts.
The Distagon T* 3,5/18 is a super-wide lens with 99 degree field of view (on film and FX sensor Nikons like the D3 and recently announced D700 - on DX cameras this lens is equivalent to 27mm). This lens is of rectilinear design and provides dramatic perspectives for architecture, landscape and close-up photographers.
The all-metal body houses eco-friendly lens elements all sporting the Zeiss T* anti-reflective coating to minimize flaring and other stray light artifacts. The lens also includes Zeiss Color Matching Technology which provides homogenous color renditions. The lens takes 82mm filters on the front.
A non-CPU, manual focus lens, the 18mm Distagon can be programmed into newer model Nikons (D300, D700, & D3).
The lens will be available in early July 2008 (ZF mount) and Q3 2008 in ZK mount. Suggested list price is 960 Euro ( about $1500 USD ).
