High corner-to-corner resolution
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.
Clarity and contrast in any light
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.
Resolution and bokeh raised to new heights
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.
Optimum resolution at any focal length
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.
Direct Drive SSM
Two DDSSM (Direct Drive SSM) systems employing original Sony piezoelectric motors directly drive two focus groups in a floating focus configuration. The focus groups are positioned with high precision for the highest possible focus accuracy. DDSSM is quiet too, making it ideal for shooting movies as well as stills.
11 blades enhance bokeh beauty
Sony's original 11-blade circular aperture contributes to even greater bokeh quality. Design and materials have been revised to maintain a round shape, and strict circularity standards are applied to ensure that the full beauty of the lens’s bokeh is achieved without compromise.
High reliability in harsh conditions
The overall design of this lens is dust and moisture resistant for extra protection and reliable operation in challenging environments. Shoot with confidence in light rain or windy conditions. Plus, the Fluorine coated front element helps to prevent dirt and fingerprints from sticking, and make it easier to wipe dirt and fingerprints away if they do become attached to the lens surface.
