Features / Specifications

14x zoom equivalent to 27.5mm to 383mm
This single versatile zoom lens can cover the range from wide-angle shooting needed for indoor photography and snapshots to super telephoto shooting of sports action and wildlife.
High-performance optical system using ED glass and aspherical lenses
The optical system uses ED (extra-low dispersion) glass and aspherical lenses to correct the various types of aberration for producing crystal-clear sharp images and for contributing to a compact design of the entire lens body. Inner focus system that keeps the same lens length while focusing
DA lens specifically for digital SLR cameras
The lens coating, curvature, arrangement, and other factors in the design were optimized for digital image characteristics to enable minimizing of ghosting and flare. Developed specifically for digital SLR cameras, this lens has an image circle that matches the 23.5mm × 15.7mm imaging element and was designed without an aperture ring.
Minimum shooting distance of 0.45m over the entire zoom range
This lens is capable of a maximum shooting magnification of 0.28X for closeup photography. This enables capturing of small flowers and other objects with visual impact.
Zoom lock mechanism for convenient portability
This lens includes a lock mechanism for locking the zoom ring at the wide angle end where lens length is shortest. This prevents unintentional changing of the lens length while carrying around.

*This lens does not use the Quick-Shift Focus System.
*The DA lens is specifically for digital SLR cameras. It cannot be used with 35mm film SLR cameras.
