Zeiss FE 21mm f2.8 Loxia - 3877
Compact, wide-angle and powerful – these are the properties that make the super wide-angle Loxia 2.8/21 so special. The optical design has been specially developed for high-resolution, full-frame sensors of the mirrorless Sony α series. A system expansion through the new ZEISS Loxia – in a focal length range that has a long tradition at ZEISS.
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.
