Pairing an all-manual control-set with a digitally-optimized design, the ZEISS Loxia 50mm f/2 Planar T* Lens is a normal prime lens for full-frame Sony E-mount mirrorless digital cameras. Its manual focus design has been developed in specific regard for use with electronic viewfinders, and also features a manual aperture ring that can be 'de-clicked' for silent operation best-suited for filmmakers. Based on the symmetrical Planar optical concept, this lens is adept at correcting for chromatic aberrations and distortion throughout the aperture range for maintained image consistency and clarity. Additionally, a ZEISS T* anti-reflective coating has also been applied to individual lens elements to further reduce lens flare and ghosting for enhanced image clarity and contrast. Serving as a unique option for the contemporary image-maker, the ZEISS Loxia series of lenses are built for the imaging demands of modern full-frame digital cameras, yet are founded upon conventional manual controls.

Offering a perspective reminiscent to normal eyesight, the 50mm focal length pairs well with the fast f/2 maximum aperture for greater control over focus position and performance in low-light conditions. Furthermore, the handling details of the lens have also been enhanced for maximum feedback and precision, including a long 180° focus throw, clearly engraved scale markings, and a robust, all-metal construction with weather-resistant lens mount gasket. Additionally, the lens is fitted with an electronic interface that conveys all EXIF data to the camera and can also be configured to automatically activate camera-based focusing aids during use.
