Product description

• Loxia 21mm f/2.8 Lens for Sony E Combining an expansive field of view with a compact form factor, the Loxia 21mm f/2.8 from ZEISS is a sleek wide-angle prime, designed for full-frame Sony E-mount mirrorless cameras. Based on the Distagon optical concept, this lens uses four anomalous partial dispersion elements and one aspherical element to provide a marked reduction in chromatic and spherical aberrations for improved color rendering, sharpness, and clarity. For minimizing flare and ghosting, an enhanced ZEISS T* anti-reflective coating has also been applied to benefit working in difficult lighting conditions.
  
  Loxia-series lenses are distinguished by their manual focus operation along with a manual aperture ring that can be de-clicked for silent operation; making them especially suitable for filmmaking applications. Loxia lenses are also characterized by their compact form factor and all-metal lens barrel, which incorporates engraved focusing and depth of field scales, for fine-tuned control. Additionally, the lens body sports a dust- and moisture-sealed design to permit its use in trying environments.
  • Wide-angle prime is designed for full-frame Sony E-mount mirrorless cameras, however can also be used with APS-C models where it provides a 31.5mm equivalent focal length
  • Bright f/2.8 maximum aperture suits working in available-light conditions and is also well-suited for astrophotography use.
  • Distagon optical concept affords high sharpness, well-corrected image quality from edge-to-edge, and very low field curvature.
  • Four anomalous partial dispersion elements are used to significantly reduce color fringing and chromatic aberrations for increased clarity and color fidelity.
  • One aspherical element controls distortion and spherical aberrations in order to produce greater sharpness and more accurate rendering.
  • ZEISS T* anti-reflective coating has been applied to each lens surface to help minimize reflections and provide greater contrast and color fidelity.
  • Manual focus design is benefitted by focusing and depth of field scales along with a 90° focus ring rotational angle and hard stops at both infinity and minimum focusing positions.
  • Manual aperture ring has clicked indicators throughout 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.
  • Weather-resistant construction includes internal seals to guard against dust and moisture as well as a blue sealing ring at the lens mount to protect the lens-camera interface.
  • 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.
• Loxia 35mm f/2 Lens for Sony E Marrying traditional handling with a digitally-optimized design, the ZEISS Loxia 35mm f/2 is a compact wide-angle prime for Sony E-mount mirrorless cameras. Utilizing a nearly symmetrical optical layout based on the Biogon concept, this lens incorporates one element made from anomalous partial dispersion glass in order to suppress chromatic aberrations and distortion for improved clarity and sharpness. An enhanced ZEISS T* anti-reflective coating has also been applied to significantly reduce ghosting and lens flare for improved contrast and color fidelity.

  • Wide-angle prime is designed for full-frame Sony E-mount mirrorless cameras, however can also be used with APS-C models where it provides a 52.5mm equivalent focal length
  • Bright f/2 aperture helps to achieve a more compact, portable form factor while also remaining versatile for use in a variety of lighting conditions.
  • Biogon optical concept benefits the wide-angle focal length by helping to virtually eliminate distortion for clean, realistic rendering.
  • One anomalous partial dispersion element is used to significantly reduce color fringing and chromatic aberrations for increased clarity and color fidelity.
  • ZEISS T* anti-reflective coating has been applied to each lens surface to help minimize reflections and provide greater contrast and color fidelity.
  • Manual focus design is benefitted by focusing and depth of field scales along with a 180° focus ring rotational angle and hard stops at both infinity and minimum focusing positions.
