The new Carl Zeiss ZF.2 / ZE 15mm f/2.8 Distagon for Nikon or Canon offers unprecedented optical performance in an ultra wide angle lens, with superb build quality and ergonomics.

Introduction
As digital camera sensor resolution increases, the demands on lens performance rise, with many lenses inadequate to the task of ultra high resolution DSLRs like the 36-megapixel Nikon D800. The exciting and newly developed optical formula of the Zeiss 15mm f/2.8 Distagon for Canon or Nikon DSLRs is an answer to those demands in the ultra-wide realm. The Zeiss 15/2.8 Distagon offers an unprecedented level of performance that makes the photographer’s job easier, because its image quality reduces or entirely eliminates the need for post-processing to correct image flaws.

Ergonomics And Build Quality
The Zeiss 15mm f/2.8 Distagon is built of metal and glass to the same superb standards as the rest of the ZF.2/ZE lens line. In this age of plastic lenses, the 15/2.8 Distagon stands out for its superb construction. It is not a small lens, but it is not an overly large or heavy lens either. It has proven to be a joy to work with. The lens balances very comfortably and naturally on a mid-size DSLR, avoiding the front-heavy and bulbous design of lenses like the Nikon 14-24/2.8G zoom.

The advanced design of the 15/2.8 Distagon requires exacting assembly tolerances. With all Zeiss lenses, a good-size sample of the first production run of both ZF. 2 (Nikon) and ZE (Canon) lenses are carefully checked for variation and MTF, to verify that construction tolerances are being fully met. Only once those preproduction lenses are fully tested is production for public sale commenced. In fact, each batch of glass has to be carefully checked for its refractive properties, because no batch is quite the same! Zeiss also checks each production lens for MTF.
