Frequently Asked Questions - AF-S TELECONVERTER TC-20E III NIKON

Which lenses are compatible with the TC-20E III?

The TC-20E III is compatible only with AF-S and AF-I NIKKOR lenses. Check the list in the manual for exact models. Some lenses (like the 105 mm VR Micro) do not support autofocus.

How does light loss affect exposure?

Using the teleconverter reduces the effective aperture by 2 stops. For example, a lens set to f/2.8 becomes effectively f/5.6. Modern cameras compensate automatically; on older bodies, use wide-open metering or stop-down metering.

Can I use autofocus with all compatible lenses?

No. Autofocus works only if the effective aperture is f/5.6 or brighter. With a maximum aperture lens of f/4, autofocus is possible; with f/5.6, it is sometimes limited. Refer to the table in the manual for valid combinations.

How to clean the teleconverter?

Use a blower to remove dust. For stains, moisten a soft cloth with ethanol (alcohol) and wipe from center to outer edge. Never use solvents like benzene or thinner.

What safety precautions should be taken?

Never look at the Sun through the lens or viewfinder. Do not use the device near flammable gas. Keep small parts out of reach of children. If the device emits smoke or an odor, remove the battery and contact an authorized technician.

How to mount the teleconverter?

1. Turn off the camera. 2. Align the mounting index of the teleconverter with the lens index. 3. Turn the teleconverter counterclockwise until it clicks. To remove, press the unlock button and turn in the opposite direction.

Does the teleconverter affect image quality?

Yes, there may be a slight loss of sharpness and contrast. The TC-20E III uses an aspherical lens to minimize aberrations. Results depend on the lens and camera used.

Can I use the teleconverter with a zoom lens?

Yes, with some AF-S zooms like the 70-200 mm f/2.8. Autofocus may be limited depending on focal length and aperture. Check the list of compatible lenses in the manual.

How to store the teleconverter?

Attach the front and rear caps. Store it in a cool, dry place, away from direct sunlight and chemicals like camphor or naphthalene.

What is the warranty of the TC-20E III?

The warranty depends on the retailer and country. Nikon generally offers a one-year limited warranty. Check the warranty certificate provided with the product. Repairs must be performed by a Nikon authorized service center.

Thank you for purchasing the AF-S Teleconverter. Before using this teleconverter, please read these instructions and refer to your lens' and camera's User's Manual.

■ Major features

• This teleconverter doubles the prime lens' focal length with a two-stop loss in effective aperture.
• Because your AF-S Teleconverter has CPU contacts, and features autofocus, meter coupling and minimum aperture coupling, you can fully take advantage of prime lens' features.
• This teleconverter employs aspherical lens, which minimizes optical interference of the prime lens.

Important

• This teleconverter is exclusively for the AF-S or AF-I NIKKOR lens (p.15); other lenses cannot be used.
• The functions of the lens attached depend on the camera in use. For details, refer to the lens' User's Manual.
  • Refer to the Focusing (p. 18) for available autofocus and focus assist.

■ Recommended focusing screens

Nikon offers a variety of interchangeable focusing screens for Nikon F6 or F5 cameras, to suit any type of lens or picture-taking situation. Those recommended for your teleconverter/lens combination are listed on pages 144–145.

◎= Excellent focusing
○= Acceptable focusing

Slight vignetting or moire phenomenon affects screen image, but film image shows no traces of this.

●= Acceptable focusing

Split-image rangefinder, microprism or cross-hair area is dim; focus on the surrounding matte area.

( )= Indicates degree of exposure compensation required in Center-Weighted metering. See User's Manual of the camera body for more details.
☐= Exposure measurement not possible; teleconverter/screen combination permits only focusing operation.

Blank box means not applicable. Since type M screen can be used for both macro photography at a 1:1 magnification ratio or higher and for photomicrography, it has different applications than other screens.

■ Attaching to the lens

When removing the lens from the camera body to attach the teleconverter, make sure that the camera's power is turned off and avoid direct sunlight.
