The 16-35mm f/2.8 Carl Zeiss T* Wide-Angle Zoom Lens is a professional-grade, bright zoom lens specifically designed for the Sony Alpha SLR series (also compatible with Minolta Maxxum series) DSLR cameras. Carl Zeiss' optical design and anti-flare T* (T-Star) coatings used for this lens help to reduce flare and to increase contrast, in addition to the aspherical, extra-low dispersion, and super extra-low dispersion glass elements.
When used with a digital SLR camera with an APS-C sized sensor, the equivalent 35mm focal length for this lens becomes 24-52.5mm. With its wide angle zoom range and its constant aperture of f/2.8, in conjunction with the Super SteadyShot image stabilization system of the Sony Alpha DSLR camera system, this lens will provide excellent results even when hand-holding the camera with available light.
