A photographer on the move needs to control things quickly and easily.
The zoom determines how big or large the subject is in the frame, image stabilization helps reduce shutter speeds and minimise any vibration whilst the large maximum aperture gives rich bokeh and high-speed AF keeps up with any movement.
This lens allows the photographer to control all the four elements with their left hand, leaving no room for uncertainty.
This workhorse of a lens brings out the maximum potential of the camera and the photographer.
23 elements shape the light
Designed for clarity and strong contrast, this lens captures every detail in each scene. The Nano GI (Gradient Index) coating reduces ghosting and lens flair when shooting into strong light. The use of six ED lens elements including one Super ED (extra-low dispersion) lens minimises chromatic aberration to achieve a high level of image resolving power. The lens configuration and coating, has been applied to deliver clarity, free of dullness or haziness, allowing the photographer to capture what their eyes see.
This is neither a long-distance runner or a sprinter. The lens makes a dash from the minimum shooting distance to infinity, and back again repeatedly. There are three requirements. It must be fast, quiet and maintain balance across its zooming range and at any shooting distance, so as not to have any impact on your grip holding the lens. The balanced form eliminates camera shake for high-speed shooting.
