ZEISS Loxia 2.4/25

Magical settings.

Powerful, wide-angle and compact – these are just some of the features of the ZEISS Loxia® 2.4/25. The Distagon® optical design has been specially developed for high-resolution, full-frame sensors from the Sony α series mirrorless cameras. This expands the ZEISS Loxia 2.4/25 in a host of ways.

Despite its compact design, the universal wide-angle ZEISS Loxia 2.4/25 lens offers outstanding image performance across the entire image field of a full-frame sensor. Whether it’s for landscapes, architecture shots or subjects in close-up against a broad background, this focal length with its large image angle is an excellent addition to the ZEISS Loxia lens family – and a universal new lens for wide-angle fans who want to capture even the tiniest details in a photo or video.

The ZEISS Loxia lenses were specially developed for mirrorless full-frame cameras from the Sony α series. What’s special about them? You can enjoy the combined benefits of leading-edge mirrorless system cameras and the creative possibilities of “traditional” manual focus photography.

Last but certainly not least, ZEISS Loxia lenses provide you with everything you need for top-quality video recordings – the unique DeClick feature for continuous aperture adjustment is just one excellent example.

  • Features

    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 focal plane. The precise engraving in meter and feet, and the depth of focus scale provide additional support for manually focusing.

    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.

    Immensely compatible

    The ZEISS Loxia lenses are suitable for use with the mirrorless Sony Alpha cameras with E-mount and were optimized for sensors up to full 35 mm format (24 x 36 mm). With the ZEISS Loxia lenses, the aperture is controlled manually. This allowed the integration of the so-called DeClick feature of the mechanical aperture ring. The cameras feature the corresponding automatic exposure control (A) and manual exposure control (M).

    Lens Design

    ZEISS Loxia 2.4/25

    Originally developed for SLR cameras requiring a long back focal distance for short focal lengths because of the mirror box (the distance between the back lens element and the film plane must be considerably longer than the focal length), the Distagon lenses (retrofocus design) are also ideal for mirrorless system cameras thanks to their optimized ray path. Even with longer focal lengths, the high-performance Distagon optical design enables consistently good correction all the way to the corners of the image and very low field curvature.
