Identification

• A digital conversion lens increases the focal range of your existing lens. It can do everything from increased magnification to extreme zooming out functions that create a wide-angle effect.
  
  

Different Models

• There are several types of digital conversion lenses. A macro converter increases magnification on your camera significantly, while a tele-converter lens provides additional zoom. Finally, a fish-eye, or wide-angle converter, allows you to zoom out further, giving your shot a sphere effect.
  
  

Considerations

• Digital conversion lenses are often charged with distorting pictures. It is possible that some distortion of images will occur, but this does not affect every shot a digital conversion lens takes. In fact, adjusting your camera's aperture settings generally eliminates the distortion effect.
