Zeiss Otus 28mm f/1.4 lens
The new lens is marketed as “The World’s best wide angle lens“. There is a Zeiss 55mm and a Zeiss 85mm lens in this same lens family as well. The lens design is quite complex: 16 lens elements in 13 groups, including floating elements as well, which is usually used in Macro lenses to improve close focus performance.
This is a wide angle manual focus lens for Canon and Nikon FF cameras. The Canon EF mount version has ZE, the Nikon F mount version has a ZF.2 moniker.
The weight of the lens is 1.35 and 1.39 kg respectively, so it is not a mirrorless wonder, but a heavy beast. It is partly because of the quite bright f/1.4 aperture. This bright aperture makes the lens much more interesting: night photos, urban landscapes can benefit from this feature.
The other reason is the metal construction, this a metal lens, with a very precise focusing ring.

The price of the lens is not yet known, but the two other brother costs around 4000 and 4500 USD respectively. The lens is expected to be available in 2016.
