The first wide-angle G Master zoom lens offers performance that will take full advantage of the high-resolution potential of the latest and future camera bodies. The most advanced Sony optical and mechanical technologies come together to deliver extraordinary rendering and clarity.
Uncompromised optical design achieves extremely high resolution and contrast. Landscapes, architecture, interiors, and other expansive subjects are captured with outstanding corner-to-corner sharpness. Aspherical elements minimize distortion, while ED (Extra-low Dispersion) glass elements effectively control chromatic aberration.
Sony’s original Nano AR Coating suppresses spurious reflections that can cause flare and ghosting in backlit and other challenging lighting situations, for consistently high contrast and clarity. Freedom from flare over a wide range of incident light angles provides greater framing and composing flexibility, particularly at wide-angle focal lengths. (1.

This lens features two Sony XA (extreme aspherical) elements with 0.01 micron surface precision. Distortion that tends to occur in wide-angle zoom lenses is meticulously controlled, as are astigmatism and field curvature. Unattractive onion-ring bokeh is effectively suppressed by XA (extreme aspherical) elements so that smooth, beautiful bokeh is achieved in out-of-focus areas.
Shooting up close at F2.8 can produce some extraordinary background bokeh. Use this capability to shoot portraits, for example, with dynamic, painterly backgrounds consisting of smooth, expressive bokeh that makes the subject stand out clearly.
Consistently high resolution is achieved from infinity to the closest focusing distance. This lens employs a floating focus mechanism with two independently driven lens groups. This system helps to reduce all types of aberration to minimum levels and thereby maintain sharp, high-resolution rendering from infinity focus for landscapes, for example, all the way down to close focus for portraits and similar subjects.
