A 50mm lens was legendary photographer Cartier Bresson’s favourite. The reason is simple: this focal length provides the equivalent field of view of the human eye on a 35mm camera, which makes for a very natural perspective. Compact, light and extremely flexible, the ZEISS Loxia® 2/50 shines in the most varied of applications. Regardless of whether it’s for street photography, landscapes, portraits or spontaneous discoveries, the ZEISS Loxia 2/50 is the ideal companion for photographic and filmic exploration.
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.

The famous symmetric lens design invented by Dr. Paul Rudolph at ZEISS in 1896. The Planar lens is the most successful camera lens design – and, by the way, the most plagiarized – ever created. It provides the lens designer with numerous means to correct aberrations extraordinarily well. And its performance is very constant over a wide range of imaging ratios, enabling such a versatile lens variety as the Makro-Planar lens.

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.
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. The precise engraving in meter and feet, and the depth of focus scale provide additional support for manually focusing.
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.
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.
ZEISS lenses are suitable for digital Sony Alpha cameras and have been optimized for film and sensors up to full 35 mm format (24 x 36 mm).
