Capture crystal-clear pictures from your full-frame Sony E-mount mirrorless cameras by using the Zeiss Loxia 21 mm f/2.8 Sony E-Mount Full Frame Wide Angle Lens. It can even be used with the APS-C models where it can provide an equivalent focal length of 31.5 mm. The lens’ bright aperture gives you the freedom to not only work in low-light conditions but to also maintain the lens’ compact overall form factor. Use the Zeiss T* anti-reflective coatings applied to each lens surface in order to minimize reflections for providing a greater image contrast, clarity, and color fidelity. Lastly, this lens is based on the revolutionary Distagon optical concept, which means that it delivers a virtually distortion-free performance that combines well with the broad angle of view.
