ZEISS Classic Planar ZE T* 50mm f/1.4 Standard Camera Lens for Canon EF Mount SLR DSLR Cameras, Black

ZEISS T* ANTI-REFLECTIVE COATING: The optical elements of ZEISS lenses feature T* anti-reflective coating on all surfaces and an optical design that guarantees images of superior brilliance at all times, even in unfavorable lighting conditions. IDEAL APERTURE WITH NINE BLADES: The nine diaphragm blades and the resulting, virtually circular aperture on ZEISS SLR lenses are crucial to favorable rendition of highlights in the foreground and background. EXCELLENT IMAGE QUALITY: ZEISS lenses offer the highest possible standards in terms of performance, reliability, and image quality. You can count on highly advanced flare control for crisp and brilliant images, and virtually zero geometric distortion. PRECISE MANUAL FOCUS: Manually focusing a lens means controlling the image result from your fingertips. A good ergonomic design makes all the difference. ZEISS lenses stand out with their large rotation angle which enables precise focusing. ELABORATE STRAY LIGHT REDUCTION: We combine various elaborate techniques to reduce unwanted stray light, such as the famous ZEISS T* anti-reflective coating that is applied to all lens element edges to ensure that reflections are prevented from the start.
