Wide-range zoom lens designed for full-frame E-mount cameras

Constant f/4 maximum aperture enables greater consistency throughout the zoom range

Features a circular aperture diaphragm that, through the use of curved blades, keeps the aperture almost perfectly circular from its wide-open setting to when it is closed for smoother, more natural defocusing highlights

Optical SteadyShot image stabilization works to minimize the appearance of camera shake by up to four shutter speed steps to benefit shooting handheld in dim lighting

Five aspherical elements, including one AA (advanced aspherical) element, and three ED elements helps to reduce chromatic aberrations throughout the zoom range while also maintaining a compact form-factor

Carl Zeiss T* anti-reflective coating enhances contrast, clarity, and color reproduction by countering the effects of lens flare and ghosting

Only the middle groups of the optical system move to achieve focus, so the overall length of the lens does not change when focusing. Also, the filter thread at the front of the lens does not rotate, which is convenient when using a polarizing filter
