The Vario-Tessar T* FE 16-35mm f/4 ZA OSS Lens from Sony will satisfy nearly all the wide-angle needs of full-frame E-mount shooters. The flexible wide zoom is characterized by a constant f/4 maximum aperture, making this an ideal lens for streets, landscapes, cityscapes, and other subjects requiring a broad field of view and the inherent versatility of a zoom.

ZEISS Optical Design
- Based on the ZEISS Tessar optical concept, this lens uses a design with 12 elements in ten groups that help ensure a smaller overall lens size along with reduced flaring, distortion, and chromatic aberrations.
- 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.
- The rounded seven-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus 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.
- Three extra-low dispersion glass elements are featured in the lens design to help reduce chromatic aberrations and color fringing for improved clarity and color neutrality.
- Five aspherical elements, including one large-diameter Advanced Aspherical (AA) element, are incorporated in the lens design to reduce astigmatism, field curvature, coma, and other monochromatic aberrations.
Image Stabilization, AF, and Handling
- Optical SteadyShot image stabilization helps to minimize the appearance of camera shake for sharper imagery when shooting handheld with slower shutter speeds. This stabilization system can also be combined with a select camera's sensor-shift type image stabilization for more effective control of camera blur.
- A linear autofocus motor and internal focus design provide quick and precise autofocus performance and enable accurate and silent focusing while recording videos.
- Dust- and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures.
