Lens Description: Featuring a compact form factor well-suited for full-frame Sony E mount mirrorless cameras, the Loxia 21mm f/2.8 Lens from Zeiss is a wide-angle prime based on the Distagon optical concept for a marked reduction in distortion as well as consistent, even illumination and sharpness from edge to edge. The optical design also incorporates four anomalous partial dispersion elements and one aspherical element to control chromatic aberrations and increase overall clarity and color accuracy. A Zeiss T* anti-reflective coating has also been applied to lens elements to minimize lens flare and ghosting for greater contrast.
