Digital Tele-Converter
The focal length of the lens can be increased by an equivalent of 
 
1.5x or 2.0x 
1.4x or 2.3x. This enables a faster shutter speed and 
less chance of camera shake than the zoom (including digital zoom) used by 
itself at the same zoom factor.
The images may appear coarse, however, depending on the combination of 
recording pixel (p. 68) and digital tele-converter settings used.
