The Sony E-mount Loxia 25mm f/2.4 from ZEISS is a versatile prime well-suited to a variety of shooting applications, including landscape, nature, architecture, interior, and astrophotography. An enhanced ZEISS T* anti-reflective coating has also been applied to significantly reduce ghosting and lens flare for improved contrast and color fidelity. 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. Distagon optical concept affords high sharpness, well-corrected image quality from edge to edge, and very low field curvature. One aspherical element controls distortion and spherical aberrations in order to produce greater sharpness and more accurate rendering. The manual aperture ring has clicked indicators throughout the 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.
