Based on the Zeiss Planar optical concept, this lens uses a design with 12 elements in 9 groups that helps achieve the large maximum aperture of f/1.4 while helping to minimize chromatic aberrations. A normal-length prime designed for full-frame E-mount mirrorless cameras, this 50mm f/1.4 is also compatible with APS-C models where it will provide a 75mm equivalent focal length. Fast f/1.4 maximum aperture benefits working in difficult lighting conditions and also offers a wealth of control over focus position when using shallow depth of field techniques. Zeiss T* anti-reflective coatings have been applied to each lens surface to help minimize reflections in order to provide greater image clarity, contrast, and color fidelity. One Advanced Aspherical (AA) and one aspherical element are incorporated into the optical design for effective control over astigmatism, field curvature, coma, and other spherical aberrations. One extra-low dispersion element is featured in the lens design to
