Wide-angle zoom, ZEISS quality and pop This full frame E-mount 16-35mm ZEISS Vario-Tessar zoom offers outstanding performance in a compact, lightweight package. A versatile zoom range coupled with built-in optical image stabilization makes it a great choice for snapshots, indoor scenes, group shots, landscapes, and more, especially with a full-frame α7 series body. A constant F4 maximum aperture facilitates exposure and depth-of-field control. Wide-angle impact over a useful zoom range This compact wide-angle zoom lens covers a useful focal length range with outstanding image quality, particularly when matched with an α7 series full frame image sensor. Refined optics deliver stunning images AA (advanced aspherical), aspherical, and ED optical elements add up to superior corner-to-corner performance with low distortion and colour aberration. T* coating minimizes flare and ghosting. Constant exposure at any zoom setting Maximum aperture is F4 at all focal lengths so the user can zoom and shoot at any aperture without having to keep track of changes in exposure settings or depth of field. Sharp and clear in any situation Optical SteadyShot image stabilization compensates for camera shake that can blur images when shooting handheld, for sharp, clear night scenes and low-light indoor shots. Lens Configuration Legendary ZEISS quality manufactured and calibrated specifically for Sony imaging products. The T* coating contributes to exquisite rendering and contrast. MTF Chart MTF (Modulation Transfer Function) describes how well a lens can reproduce fine details, measured as the degree of contrast achieved between finely spaced lines.
