- Shuttle-Shot Technology
- The lens has added capability when zooming, using the shuttle shot switch. At the touch of a button, the lens can move to a pre-programmed point, going back and forth. This can be used both creatively while providing a no hassle way of verifying focus.
- Improved Image Quality
- The lens element design greatly reduces aberrations and image distortions. These advances contribute to more balanced imaging from center to edge throughout the aperture range
- Integral 2x Extender
- For instant close-up images the lens has a switch that inserts an element that doubles the focal length at any point in the zoom range. Instead of using the zoom function, the extender gives immediate close up images.
