Sony Vario-Tessar T* FE 24-70mm f/4 ZA OSS Overview
Walk around all day with the Vario-Tessar T* FE 24-70mm f/4 ZA OSS Lens from Sony, a compact full-frame option that covers wide-angle to short telephoto perspectives for working with a variety of different shooting styles and subjects. A constant f/4 aperture makes operation smooth and consistent throughout the zoom range. The lens further benefits from the use of one extra-low dispersion element and five aspherical elements to combat aberrations as well as a Zeiss T* anti-reflective coating to keep flare and ghosting to an absolute minimum. The lens is fast to focus as well due to the linear autofocus motor and an internal focus design. Additionally, the dust- and moisture-resistant lens is equipped with Optical SteadyShot image stabilization to reduce the effects of camera shake, and it has a seven-blade circular diaphragm for smooth bokeh.Based on the Zeiss Tessar optical concept, this lens uses a design with 12 elements in ten groups that helps ensure a smaller overall lens size along with reduced flaring, distortion, and chromatic aberrations.Covering wide-angle to short telephoto perspectives, this compact 24-70mm can quickly become a go-to lens for Sony’s full-frame E-mount cameras. It can also be used on APS-C format cameras where it will provide a 36-105mm equivalent zoom range.A constant f/4 maximum aperture offers consistent performance throughout the zoom range and also lends greater control over focus position for shallow depth of field techniques.Zeiss T* anti-reflective coatings have been applied to each lens surface to help minimize reflections in order to provide greater image clarity, contrast, and color fidelity.One extra-low dispersion glass element is featured in the lens design to help reduce chromatic aberrations and color fringing for improved clarity and color neutrality.Five aspherical elements are incorporated in the lens design to reduce astigmatism, field curvature, coma, and other monochromatic aberrations.
