Sony SEL50F14Z Planar T x FE 50mm f/1.4 ZA Lens Black

High-performance 50mm prime lens featuring a large F1.4 maximum aperture with outstanding contrast and resolution that are hallmarks of the ZEISS brand. The bright F1.4 maximum aperture offers excellent low light performance and adds to the 11-blade aperture and aspheric elements for gorgeous bokeh. 12 Elements in 9 Groups with two aspherical elements, including a high-precision AA (advanced aspherical) type and ED (Extra-low Dispersion) glass element, help maintain outstanding contrast and resolution right out to the image periphery. ZEISS T* coating delivers superior contrast and resolution.  50mm wide aperture Prime lens with ZEISS Planar design  Center to corner sharpness with outstanding resolution  Bright F1.4 maximum aperture with excellent low light performance  12 Elements in 9 Groups with Advanced Aspheric and ED glass  ZEISS T* coating delivers superior contrast and resolution  11-blade aperture and aspheric elements for gorgeous bokeh  Ring Drive SSM for fast, quiet and precise focusing  Aperture ring with a selectable click ON/OFF switch  AF/MF switch for direct auto/manual focus control  Dust and moisture resistant for robust reliability 50mm wide aperture Prime lens with ZEISS Planar design High-performance 'normal' 50mm prime lens is the ideal focal length for most photographers. The bright F1.4 maximum aperture delivers excellent low-light performance and control over defocused backgrounds. A state-of-the-art optical design includes 12 Elements in 9 Groups with Advanced Aspheric and ED glass - reducing spherical aberration and distortion to an absolute minimum for a flat image plane that is consistent with the Planar name. Center to corner sharpness with outstanding resolution 12 Elements in 9 Groups including Aspherical lens design which dramatically reduces spherical aberration while also reducing lens size and weight. Spherical aberration is a slight misalignment of the light rays projected on the image plane. This is caused by differences in refraction at different points on conventional spherical lenses which degrade image quality in large-aperture lenses. Specially shaped "aspherical" elements near the diaphragm restore alignment of light rays at the image plane, maintaining high sharpness and contrast even at maximum aperture and can also be used at other points in the optical path to reduce distortion. While ED glass dramatically reduces chromatic aberration and provides superior contrast across the entire image, even at large aperture settings. ZEISS T* coating delivers superior contrast and resolution Coated optics were pioneered by Carl Zeiss - and this s
