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. 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.

One Advanced Aspherical (AA) and two aspherical elements are incorporated into the optical design for effective control over astigmatism, field curvature, coma, and other spherical aberrations.
