Best Loxia 35mm f/2 Biogon T* Lens for Sony E Mount Wide Angle

A lens with an angle of view so wide that it can capture very much of the life around us in a single frame – this is what the name Biogon originally means. A focal length, produced with an almost symmetric lens design of surprising compactness, featuring the typical advantages of symmetrical lens designs: distortion is extremely well controlled, and so is color correction and image field flatness. 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).

Features:

• Biogon with 9 lens elements in 6 groups
• Lens made of special glass with anomalous partial dispersion
• Designed specifically for full-frame E-mount mirrorless digital cameras
• Can also be used with APS-C sized E-mount cameras
• Enables greater control over focus placement for shallow depth of field and selective focus applications.
• Made from anomalous partial dispersion glass helps to suppress chromatic aberrations for greater clarity
• Lens features nine elements in six groups that are arranged in a nearly symmetrical design
• Zeiss T* anti-reflective coatings have been applied to each lens surface to help minimize reflections in order to provide greater image clarity, contrast and color fidelity.
• Manual focus design is accentuated by a knurled metal focusing ring, 180° focus ring rotational angle, and engraved depth of field and distance scale markings.
• The manual aperture ring has 1/2-stop clicks throughout the f/2 to f/22 aperture range
• Using the included De-Click Tool, this ring can be mechanically ‘de-clicked’ for smooth, silent rotation throughout the aperture range; making it ideal for video applications.
• The lens mount is fitted with an electronic interface that conveys all lens EXIF data to the camera and can also be configured to automatically activate the camera’s focusing magnification function when turning the focus ring.
• An all-metal lens barrel is fitted with a weather-resistant gasket at the lens mount to protect against moisture and dust from reaching the image sensor or rear lens element.
