Capture dynamic landscapes and wide perspectives with the full-frame A-mount Vario-Sonnar T* 16-35mm f/2.8 ZA SSM II Lens from Sony. Featuring a constant f/2.8 aperture, shooters will enjoy a consistent exposure throughout the zoom range as well as the ability to create images with a shallow depth of field. The lens also enjoys improved performance with an optical design that features one Super ED, one ED, and three aspherical elements as well as Zeiss' T* anti-reflective coating, which all help to minimize aberrations and improve sharpness and contrast. Operation is made easy with a fast and quiet Super Sonic wave Motor (SSM) for autofocus and the inclusion of both a focus hold button and focus mode switch.

It also benefits from an internal focus design and offers photographers a minimum focus distance of 11" for getting close to their subjects. Additionally, it has a nine-blade circular diaphragm for smooth bokeh as well as a dust- and moisture-resistant construction.Based on the Zeiss Sonnar optical concept, this lens uses a design with 17 elements in 13 groups that helps create a relatively compact wide-angle zoom with improved contrast, a resistance to flare, and with minimal distortion and chromatic aberrations.A wide-angle zoom designed for full-frame A-mount cameras, the 16-35mm can also be used on APS-C camera systems where it will provide a 24-52.5mm equivalent focal length.A constant f/2.8 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 super extra-low dispersion element and one extra-low dispersion glass element are featured in the lens design to help reduce chromatic aberrations and color fringing for improved clarity and color neutrality.Three aspherical elements are incorporated in the lens design to reduce astigmatism, field curvature, coma, and other monochromatic aberrations.An SSM autofocus system and internal focus mechanism provides quick, quiet, and precise autofocus performance and also contributes to more natural, intuitive manual focus control.A focus hold button and focus mode switch are present on the lens barrel for intuitive tactile control and rapid access to select settings.Dust- and moisture-sealed design better permits working in inclement conditions.Rounded nine-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques..
