Zeiss has just announced the new Loxia 21mm f/2.8 E-mount lens for Sony Alpha APS-C and full frame mirrorless cameras. Price in US is $1,499.00, will be released in December, 2015 in US.
Here is detail of Loxia 21mm f/2.8 Distagon lens:
Despite its compactness, the super wide-angle ZEISS Loxia® 2.8/21 offers outstanding image performance – across the entire image field of a full-frame sensor. Whether architecture, landscape or also three-dimensional subjects in close-up against a spacious background – this focal length with its large image angle is an excellent addition to the Loxia lens family. It is an absolute must for wide-angle fans who want to capture even the tiniest details of a special moment in a photo or on film.
ZEISS Loxia lenses were specifically designed for Sony α7 cameras. This means that they can make the most of the mirrorless, full frame system, while giving you all the creative possibilities of ‘classic’ photography with manual focus at the same time.
And that’s not all: ZEISS Loxia lenses also provide everything you need to shoot high quality video, such as the unique DeClick feature for smooth adjustment of the aperture, for example.
When wide angle views go to extremes and beg the control via an SLR viewfinder, which means that the back focal distance has to be much larger than the focal length, a retrofous design called Distagon is the right choice.
