he 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. It also features a constant f/4 aperture for consistent performance and illumination throughout the zoom range. Ensuring optimal image quality, the lens design incorporates five aspherical elements, including one Advanced Aspherical (AA), three extra-low dispersion elements, and the Zeiss T* anti-reflective coating. This combination delivers images that are free from aberrations and flare.
For smooth operation, the lens uses a linear autofocus motor and an internal focusing design. Also, it is equipped with Optical SteadyShot to dramatically reduce the effects of camera shake on your images. Additionally, it has a seven-blade circular diaphragm for smooth, rounded bokeh.
