ZEISS Loxia 21mm F2.8: compact manual-focus full-frame lens for Sony E-mount
The ZEISS Loxia 21mm F2.8 is a compact manual-focus full-frame lens for Sony E-mount. Compact 21 mm f/2.8 manual-focus super wide-angle lens for full-frame Sony E-mount mirrorless cameras. Available from ZEISS at Camerahaus.
Who Is This Made For?
The Loxia 21mm F2.8 is for photographers who focus by hand and want the highest image quality their camera can record.
21 mm, f/2.8
Focal length 21 mm with an aperture range of f/2.8 - f/22; 11 / 9 lens elements / groups; angle of view 91° diagonally.
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 focal plane.
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.
Virtually Distortion-Free Optics
Dramatic perspectives and a view from extraordinary image angles - ZEISS lenses open up new composition possibilities. Distortion would disrupt the composition because straight lines, whose image does not go through the image center, would be reproduced with a curved shape. This annoying effect is accordingly and largely compensated through elaborate optical designs at all focal lengths.
High-grade Full-Metal Casing
Tangible quality that holds its value is what qualifies ZEISS lenses for decades of hard use. A precision-engineered full-metal casing, grippy focus and aperture rings made of metal, and a tough front bayonet and filter screw guarantee stunning photographic results. A special sealing ring on the bayonet also protects the interface between the camera and the lens.
Close focus
Focusing range 0.25 m, for a maximum image ratio of 1:7.81.
