nikon 2x teleconverter tc-200

Sample picture taken with a Nikon TC-200 Teleconverter

A Teleconverter is an optical device that goes between your camera and lens to increase the focal length. There are usually two lengths available - 1.4X and 2X. The number is a multiplier. For example, a 2X teleconverter on installed on a 105mm lens results in a 210mm focal length. A teleconverter is an inexpensive way to get a new effective lens focal length!

Like most things in life, nothing is free - the 2X teleconverter sucks up two additional stops of light, turning a 105mm f2.8 into an f5.6. Also, the longer focal length means that you will need a faster shutter speed, which will make hand-holding the lens with teleconverter in low light more difficult.

A teleconverter is a relatively cheap way to get a longer focal length. Just make sure to take into account the loss of light to be sure it will still be useful to you.

The TC-200 is compatible with almost any Nikon AI or AIs compatible lens up to 200mm in focal length. It does not relay autofocus information from an AF lens, so while you can attached it to a modern body and lens, autofocus will not work. The TC-200 is made up of 7 elements in 5 groups.
