A teleconverter is an optical component that fits between camera and lens and increases the focal length without altering the minimum focusing distance. They are most commonly made in l.4x and 2x versions - although l.7x and 3x versions are also produced. Therefore, a 200mm telephoto combined with a l.4x converter would be equivalent to 280mm, while the same lens coupled with a 2x multiplier would be transformed into a 400mm lens. Converters are relatively inexpensive, light and compact, so are a convenient and economical way to expand the overall flexibility of your kit, making them a great choice for nature photographers in particular. However, there are disadvantages to using converters.
