Power through any extended photo session with this Sony 16-35mm f/4 E-mount lens. It's ideal for shooting wide-angle views of buildings or expansive landscapes so that your audience can fully appreciate the world around you. The glass incorporates T* optical coatings to ensure you get the most out of each photo, reducing lens flare, radial blur and chromatic effects substantially, and aspherical lens elements in this E-mount lens precisely target the sensor for edge-to-edge sharpness.

An internal focusing mechanism keeps this wide-angle lens the same length across the entire zoom so that it feels natural in your hand and so that it's easy to handle when shooting video, and axial stabilization means that you can use it even in lower light situations, such in nightclubs and for night shoots. When you're shooting wide open using the f/4 aperture, the circular shape produces creamy bokeh that brings your subject into the foreground, and the iris motor and focusing motors are super quiet so that you can ensure this Sony 16-35mm f/4 E-mount lens won't interrupt your audio soundtrack.

Features:

• Unmatched ZEISS T* (T-star) coating
  Coated optics were pioneered by ZEISS® -- and this superb lens features the ZEISS T* (T-Star) coating that virtually eliminates lens flare, internal reflection and light scattering that can otherwise occur at glass-to-air surfaces. The T* coating contributes to outstanding image quality, with high contrast and uniformly excellent resolution right out to the image edges. Not simply applied to any lens—the T* symbol only appears on multi-element lenses in which the required performance has been achieved throughout the entire optical path, therefore guaranteeing the highest quality
• Circular Aperture
  When changing your aperture to defocus the background, the light sources appear blurred. This ‘bokeh’ effect of the blurred background can be enhanced with circular aperture blades used in this lens. Conventional aperture blades have flat sides creating unappealing polygonal shaped defocussed points of light. Circular aperture overcomes this problem through the use of curved blades that keeps the aperture almost perfectly circular from its wide-open setting to when it is closed.. Smoother, more natural defocusing can be obtained as a result
• Aspherical lens elements
  Aspherical lens design dramatically reduces spherical aberration while also reducing lens size and weight. Spherical aberration is a slight misalignment of the light rays projected on the image plane, caused by differences in refraction in conventional spherical lenses which degrade image quality in large-aperture lenses. Specially shaped “aspherical” elements near the diaphragm restore alignment of light rays at the image plane, maintaining high sharpness and contrast even at maximum aperture and can also be used at other points in the optical path to reduce distortion. Well-designed aspherical elements often requires complex glass molding technology, but can reduce the total number of elements required, thus reducing overall size and weight
• ED (Extra-low Dispersion) glass
  As focal lengths get longer, lenses built with conventional optical glass have difficulties with chromatic aberration, and as a result images suffer from lower contrast, lower color quality, and lower resolution. ED glass dramatically reduces chromatic aberration and provides superior contrast across the entire image, even at large aperture settings
• Lens-based Optical SteadyShot® image stabilization
  Gyro sensors built into the lens detect even the slightest movement, and the stabilization lens is precisely shifted to counteract any image blur that might occur. The use of precision, quiet linear motors and technology inherited from high-end Sony professional camcorders results in exceptionally quiet, effective image stabilization that contributes to high-quality movies as well as stills
• Dust and moisture resistant design
  The dust and moisture resistance design makes this lens appropriate for heavy-duty outdoor use, especially when combined with a camera that employs weather resistant measures such as the Sony’s a7 series of cameras
• Internal focusing
  Only the middle groups of the optical system move to achieve focus, so the overall length of the lens does not change when focusing. Other important benefits include fast autofocusing and a short minimum focusing distance. Also, the filter thread at the front of the lens does not rotate, which is convenient when using a polarizing filter
