TELECONVERTERS

Home | Email

What do they do / how do they do it / what does it cost you?

Teleconverters (sometimes referred to as extenders) effectively increase the focal length of a lens. For example, if you mount a 2X teleconverter in back of a 100mm/4 lens, your effective lens is now a 200mm/8. There are phenomena associated with the use of teleconverters that you should be aware of before you rush out to buy one.

  1. Teleconverters accomplish their task through the use of optics to further magnify the object to be photographed. This means you are inserting more optical interfaces between the object to be photographed and the film in your camera. Each optical interface that you insert in the light path has the capability of reducing image quality - NO teleconverter can improve the image quality that was possible with the lens alone at a shorter distance, it can only enlarge the image and degrade the image to some extent.
  2. As the focal length increases, so does the apparent 'camera shake' associated with the longer focal length - you will need to take this into account by setting your shutter to a higher speed or resort to using a tripod to reduce the effect.
  3. The minimum focusing distance that was possible with the lens alone changes minimally. If your 100mm lens alone will focus down to 18 inches and you attach a 2X teleconverter, you now effectively have a 200mm lens that focuses down to 18 inches + the physical length of the teleconverter.
  4. The amount of light entering the camera body through the lens-teleconverter combination is reduced. In the case of your 100mm/4 lens and a 2X teleconverter, your effective lens is now a 200mm/8. Since less light (actually ¼ as much) is entering the camera, you must compensate for it. In SLR cameras, the meter reads the light entering the body, so proper exposure is still obtained by reading your camera meter as always. However, less light means that exposure times may need to be increased through the use of slower shutter speeds - again requiring the use of a tripod and perhaps a remote shutter release. You may have to switch to a faster film to offset this effect also.
  5. In general, teleconverters are designed for short (200mm and less) or long (300mm and greater) lenses and can not be switched back and forth. In general, you can expect more image degradation with a 2X teleconverter than with a 1.4X teleconverter. In general, 3X teleconverters are nearly worthless because of image degradation.
  6. Always read your lens specification sheet before attaching a teleconverter - damage may occur otherwise.

Having said all that, there are instances where purchasing a really long lens is not possible because of your circumstances and the only way you can get that photo is by a really long lens. Go for it - buy a teleconverter - but now you know what the pitfalls are. A good teleconverter can be a blessing - a bad one can be a nightmare.

Nikon Lens - Teleconverter Compatibility Chart Notes
Please note in the charts which follow that Auto Focus lens will only focus Manually with the teleconverters shown marked with a plain YES. Only newer generation teleconverters are shown. If any color appears in the cells across from each lens, either the teleconverter is not usable because it can not be mounted -or- vignetting or other deterioration will ruin the photograph.
YES Teleconverter is compatible, provides manual focus (MF) only, will not provide autofocus (AF).
YES(AF) Teleconverter is compatible, will provide autofocus (AF) with F5, F4, F100, F90 & F70 bodies.
1

Usable, but without filter.

2

Usable, but at a close focused distance vignetting or other image deterioration may occur

3

Usable, but vignetting or other image deterioration may occur

NO

Not usable, because it cannot be mounted, or vignetting or other deterioration will ruin the photo. Never attach the TC-14A to the GN-Nikkor 45mm f/2.8, the lens or TC-14A could be damaged.
