Also, through the use of one extra-low dispersion element, one Advanced Aspherical, and three aspherical elements, users will enjoy sharp, aberration-free imagery., the 16-70mm is equipped with a linear motor and uses an internal focus design. It also has Optical SteadyShot image stabilization to reduce the effects of camera shake, especially at longer focal lengths. Additionally, the lens can focus as close as 13.8" and it has a seven-blade circular diaphragm for smooth bokeh. A versatile mid-range zoom for APS-C-format E-mount cameras, this 16-70mm lens provides a wide-angle to short telephoto 24-105mm equivalent focal length that works for anything from vast landscapes to tight portraits to distant subjects. 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. Optical SteadyShot image stabilization helps to minimize the appearance of camera shakes 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. The rounded seven-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.
