Sony Vario-Tessar T FE 24-70mm F4 ZA OSS Camera Lens - SEL2470Z

Sony SEL2470Z Black Vario-Tessar T FE 24-70mm F4 ZA OSS Camera Lens

Enjoy consistent performance from this Sony 24-70mm f/4 camera lens. This full-frame lens connects to your E-mount camera so that you can use it in a wide range of scenarios. Take photos of landscapes, architectural stills or sweeping city or nightscapes, or get in close to photograph portraits of people whether in the studio or out and about. It includes dust and moisture resistance thanks to reliable seals that keep this Sony lens completely safe, letting it resists showers and storms.

Extra-low dispersion glass and aspherical lens elements ensure this Sony lens produces high-quality photos with absolute sharpness from the center to the corners. In addition, optical coatings help prevent distortions such as chromatic aberration, ghosting and flare from affecting the photo for maximum quality. Even the aperture helps with quality, as it's circular so that when bokeh is formed, each highlight is a pleasing circular shape rather than a polygon. Consequently, when it's at its widest, this Sony 24-70mm f/4 camera lens produces creamy backgrounds, letting your subject stand out.

Features

• Circular Aperture
  When changing your aperture to defocus the background, the light sources appear blurred. This 'bokeh' effect of the blurred background can be enhanced with circular aperture blades used in this lens. Conventional aperture blades have flat sides creating unappealing polygonal shaped defocussed points of light. α lenses overcome this problem through a unique design that keeps the aperture almost perfectly circular from its wide-open setting to when it is closed by 2 stops. Smoother, more natural defocusing can be obtained as a result.
• ED (Extra-low Dispersion) glass
  As focal lengths get longer, lenses built with conventional optical glass have difficulties with chromatic aberration, and as a result images suffer from lower contrast, lower color quality, and lower resolution. ED glass dramatically reduces chromatic aberration at telephoto ranges, and provides superior contrast across the entire image, even at large aperture settings. Super ED glass provides enhanced compensation for chromatic aberration.
• Aspherical lens elements
  Aspherical lens design 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. Well-designed aspherical elements can reduce the total number of elements required in the lens, thus reducing overall size and weight. Advanced Aspherical (AA) elements are an evolved variant, featuring an extremely high thickness ratio between the center and periphery. AA elements are exceedingly difficult to produce, relying on the most advanced molding technology to consistently and precisely achieve the required shape and surface accuracy, resulting in significantly improved image accuracy and quality.
• Carl Zeiss T* (T-star) coating
  Coated optics were pioneered by Carl Zeiss® - and this superb lens features the Carl Zeiss T* (T-Star) coating that virtually eliminates lens flare, internal reflection and light scattering that can otherwise occur at glass-to-air surfaces. The T* coating contributes to outstanding image quality, with high contrast and uniformly excellent resolution right out to the image edges. Not simply applied to any lens - the T* symbol only appears on multi-element lenses in which the required performance has been achieved throughout the entire optical path, therefore guaranteeing the highest quality.
• Lens-based optical image stabilization
  Gyro sensors built into the lens detect even the slightest movement, and the stabilization lens is precisely shifted to counteract any image blur that might occur. The use of precision, quiet linear motors and technology inherited from high-end Sony professional camcorders results in exceptionally quiet, effective image stabilization that contributes to high-quality movies as well as stills.
• Internal focusing
  Only the middle groups of the optical system move to achieve focus, so the overall length of the lens does not change. Other important benefits include fast autofocusing and a short minimum focusing distance. Also, the filter thread at the front of the lens does not rotate, which is convenient if you're using a polarizing filter.
