Two AF-L buttons are available to be programmed based on your shooting needs.
A zoom lock switch prevents the lens from accidentally extending.
The lockable aperture ring with click/de-click function enables smooth adjustments and prevents unintentional value changes.
Optical Design
Two F Low Dispersion (FLD) and one Special Low Dispersion (SLD) elements markedly reduce chromatic aberrations and color fringing throughout the zoom range for improved clarity and color accuracy.
Five aspherical elements control spherical aberrations and distortion for increased sharpness and accurate rendering.
A water- and oil-repellant coating is applied to the front lens element to minimize any liquids from sticking to the glass.
