Nikon TC-20E III AF-S F.A.Q.

How do I attach the Nikon TC-20E III AF-S teleconverter to my camera and lens?

To attach the Nikon TC-20E III AF-S, first ensure that both your camera and lens are powered off. Remove the rear lens cap and attach the teleconverter to the lens by aligning the mounting marks. Turn the teleconverter clockwise until it locks into place. Then, attach the combined unit to the camera body by aligning the marks and turning it until it clicks.

What lenses are compatible with the Nikon TC-20E III AF-S teleconverter?

The Nikon TC-20E III AF-S is compatible with select NIKKOR lenses, primarily those with a maximum aperture of f/2.8 or larger. It works best with telephoto and super-telephoto lenses, such as the AF-S NIKKOR 70-200mm f/2.8G ED VR II. Consult your lens manual or Nikon's official compatibility chart for specific details.

Does using the Nikon TC-20E III AF-S affect image quality?

Using the Nikon TC-20E III AF-S can slightly reduce image quality due to the increased focal length and additional glass elements. However, it is designed to maintain high optical performance. Stopping down the aperture slightly can help improve sharpness and reduce chromatic aberrations.

How can I troubleshoot autofocus issues when using the Nikon TC-20E III AF-S?

If you experience autofocus issues, ensure that your camera's firmware is up to date and that the lens is compatible with the teleconverter. Check that all connections are secure and clean the lens and teleconverter contacts with a microfiber cloth. You may also switch to manual focus if autofocus is unreliable in low light or with slower lenses.

What is the best way to clean the Nikon TC-20E III AF-S teleconverter?

To clean the Nikon TC-20E III AF-S, use a blower to remove dust from the glass elements. Then, gently wipe with a microfiber cloth or lens cleaning tissue. Avoid using excessive force or liquid cleaners, as they can damage the coatings. Always replace the caps when not in use to prevent dust accumulation.

Can I use the Nikon TC-20E III AF-S teleconverter with a non-Nikon lens?

While the Nikon TC-20E III AF-S is designed specifically for Nikon AF-S lenses, it may physically fit some non-Nikon lenses. However, autofocus and metering functionality are not guaranteed, and image quality may be compromised. It's recommended to use it with compatible Nikon lenses for optimal performance.

How do I store the Nikon TC-20E III AF-S to ensure its longevity?

Store the Nikon TC-20E III AF-S in a cool, dry place away from direct sunlight. Use the lens caps to protect the glass elements and keep it in a padded case to prevent physical damage. Avoid storing in humid environments to prevent mold and fungus growth.

What should I do if there is visible dust inside the Nikon TC-20E III AF-S teleconverter?

If dust is visible inside the Nikon TC-20E III AF-S, it may require professional cleaning. Contact Nikon support or an authorized service center for assistance, as disassembling the teleconverter yourself can void the warranty and cause further damage.

Is it possible to stack multiple teleconverters with the Nikon TC-20E III AF-S?

Stacking multiple teleconverters is generally not recommended, as it can significantly degrade image quality and reduce autofocus performance. Additionally, most Nikon teleconverters, including the TC-20E III, are not designed to be stacked, which can lead to mechanical and optical issues.

How does the Nikon TC-20E III AF-S affect the exposure and aperture settings?

The Nikon TC-20E III AF-S increases the focal length by 2x, which effectively reduces the maximum aperture by two stops. For example, an f/2.8 lens becomes f/5.6. Adjust your exposure settings accordingly, as the reduced aperture may require slower shutter speeds or higher ISO settings to maintain proper exposure.
