Compact and wide-angle in one
Loxia 2.8/21

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 a series. A system expansion through the new ZEISS Loxia – in a focal length range that has a long tradition at ZEISS.

ZEISS Loxia 2.8/21 Compact and wide-angle in one

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 a7 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.

In SLR systems, when extremely large image angles are needed, the distance between the rear element and the image plane must be considerably longer than the focal length – the original field of application of Distagon lenses. This advanced retrofocus design can also be put to outstanding use in modern, highly corrected lenses with longer focal lengths.

  • Lens made of special glass with anomalous partial dispersion
  • Lens with aspheric surface

DeClick feature
One completely new feature of the Loxia lens is that you can ‘declick’ the aperture’s locking mechanism using a tool (supplied) and an adjustment screw on the bayonet surface. This means that for video applications, you can smoothly eliminate any unwanted differences in brightness as you pan the camera. This feature can also be used with other video systems whose size makes them suitable for adaption.

Precise manual focus
Manually focusing a lens means controlling the image result from your fingertips. A good ergonomic design makes all the difference. ZEISS lenses stand out with their large rotation angle which enables precise focusing. Changes are immediately visible in the viewfinder. The high-quality focusing mechanism moves smoothly without play, thus also supporting the intuitive interaction with the f
