Sharp and clear from corner to corner
Three aspherical elements, including one precision Sony AA (advanced aspherical) element, combine in a state-of-the-art optical path to effectively compensate for aberration and achieve outstanding corner-to-corner sharpness.That sharpness is maintained even at maximum aperture so optical performance is consistent at all exposure settings.

For low-light shooting and smooth bokeh
The F1.4 maximum aperture of this lens makes it easier to capture clear images in low light, even when shooting handheld. A 9-blade circular aperture design enhances its capability for stunningly beautiful background bokeh when desired. Smooth bokeh can make subjects stand out in images with deep dimensional impact.

Outstanding color and contrast
ZEISS lenses are renowned for their outstanding color reproduction and contrast. The ZEISS T* coating is an important contributing factor, effectively suppressing spurious reflections that can degrade overall image quality. Flare and ghosting are reduced for enhanced color and contrast that give images a deep, three-dimensional feel.

DDSSM delivers quiet focus speed and precision
A new DDSSM (Direct Drive SSM) system is used for precision positioning of the heavy focus group required for the full-frame format, allowing precision focusing even within the lens#s shallowest depth of field. The DDSSM drive system is also remarkably quiet, making it ideal for shooting movies where focus is constantly changing while the scene is being recorded.

Optimized for movies as well as stills
This lens is designed for moviemaking as well as for still photography. An aperture ring with switchable clicks can be turned ON for tactile feedback when shooting stills or OFF for smooth, quiet operation when shooting movies. It also features minimal focus breathing, an essential quality for movie shooting.

High reliability in harsh conditions
The lens features a dust and moisture resistant design that ensures reliable operation for professional use in harsh conditions.
