Zeiss Loxia 25mm f/2.4 for Sony E-mount

ZEISS Loxia 2.4/25Magical 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.DeClick featureOne 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 focusManually 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 opticsDramatic 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 casingTangible 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 compatibleThe 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).Technical Specifications ZEISS Loxia 2.4/25 PerformanceFocal length25 mmAperture rangef/2.4 – f/22Camera mountSony E-Mount*Format compatibilityFull FrameFocusing range0,25 m (9.84″) – ∞Free working distance0,16 m (6.42″) – ∞Angular field** (diag. | horiz. | vert.)81° / 71° / 50°Diameter of image field43 mm (1.69″)Coverage at close range (MOD)**231 x 154 mm (9.10 x 6.07″)Image ratio at minimum object distance1 : 6.4Lens elements | groups10 / 8Flange focal distance18 mm (0.71″)Entrance pupil position (front of image plane)65 mm (2.54″)FeaturesAutofocus–Image Stabilization–PhysicalFilter threadM52 x 0.75Rotation angle of focusing ring90°Diameter max.62 mm (2.44″)Diameter of focusing ring62 mm (2.44″)Length (with lens caps)88 mm (3.45″)Length (without lens caps)75 mm (2.93″)Weight393 g (0.87 lbs)
