A classic focal length and a classic design, the Canon EF-mount Planar T* 50mm f/1.4 ZE from ZEISS is a normal-length prime ideal for working with most subjects. Its bright f/1.4 maximum aperture excels in low-light conditions and also offers greater control over depth of field for using selective focus. The Planar type optical concept is a tried-and-true design that yields consistently high sharpness throughout the focusing range with even illumination throughout the aperture range. Also, a T* anti-reflective coating has been applied to individual elements to control lens flare and ghosting for improved contrast and color accuracy.
