Their specialized design gives these lenses the ideal properties for digital cameras, the compact and lightweight construction is an added bonus!
The aspherical lens complex allows freedom of design, improved performance, a reduced number of component lenses and a compact size.
This function utilizes a built-in mechanism that compensates for camera shake. It dramatically expands photographic possibilities by alleviating camera movement when shooting by hand held camera.
This lens uses a motor driven by ultrasonic waves to provide a quiet, high-speed AF.
To ensure stability in focusing, this lens moves the inner lens group(s) without changing the lens' physical length.
The exterior of this lens is EX-finished to denote the superior build and optical quality, and to enhance its appearance.
