Since it fits right over your camera's existing lens system a wide-angle and telephoto converter affects the full zoom range of your camera's lens. A wide-angle converter increases your angle of view - scenes include more of the landscape groups include more people and interiors show more of the room. A .45x wide-angle converter DOUBLES your angle of view allowing you to get twice as much in the picture (AND your telephoto setting also becomes wider; not zooming in as close). A 2.2x converter will double your camera's maximum focal length bringing things twice as close. An Opteka conversion lens can actually improve the image that your digital camera receives and it's about the only accessory that can. By eliminating flare and ghosting the ugly cousins of reflection and refraction before they get to your camera's original lens system your camera gets a much cleaner image to digitise. Plus an Opteka converter allows you to use a more optimal part of your original lens system resulting in more crisp imagery.
