Lens Features

• 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 a 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 colour 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.

 Additional Lens Benefits

• Lens weight is approximately 2 lb. The lens barrel near the mount is made of magnesium instead of aluminium, contributing to its lightweight design and allowing users to shoot longer without fatigue.
• 82mm filter thread for wide compatibility.
