The Nikon AF-S TC-20E III Teleconverter 2x Aspherical is a high-performance teleconverter designed to double the focal length of compatible Nikon lenses. Featuring an aspherical lens element, it ensures superior image quality with minimal distortion. This teleconverter is ideal for wildlife and sports photography, providing extended reach while maintaining excellent optical performance.

Doubles the effective focal length of compatible Nikon lenses, offering enhanced reach for distant subjects.

2x Magnification

Incorporates an aspherical lens element to reduce aberrations and ensure high-quality images.

Aspherical Lens Element

Designed for portability, making it easy to carry and use in the field.

Compact and Lightweight Design

Constructed to withstand challenging environments, suitable for outdoor photography.

Durable Build

The Nikon AF-S TC-20E III Teleconverter is a **Nikon F mount** telephoto accessory built for **DSLR** camera systems. Designed to cover the **full frame** format, it integrates seamlessly with Nikon F mount lenses and bodies without introducing coverage limitations on full frame sensors. The teleconverter operates as a **prime** optical element and supports **Auto and Manual focus** modes, giving photographers the ability to use autofocus when paired with compatible lenses or switch to manual when precision is required. With a weight of **330g**, it adds a manageable amount of mass to a telephoto setup. Image stabilization is **not present** in the unit itself, so shooters should rely on any stabilization available in their lens or camera body. There is no filter thread on the unit, and no hotshoe connection. For Nikon DSLR photographers already invested in the F mount ecosystem, the TC-20E III offers a native-mount teleconverter option that preserves autofocus functionality.

Doubles the effective focal length of the host lens, turning a 400mm lens into an 800mm equivalent for dramatically extended reach.

2x Focal Length Multiplier

Aspherical glass construction helps minimize spherical aberration and maintain image sharpness at the edges of the frame.

Aspherical Optical Elements

Mounts directly between compatible Nikon F mount lenses and Nikon DSLR bodies with no adapters required.

Nikon F Mount

Retains autofocus functionality when used with compatible AF-S and AF-I Nikkor lenses, allowing hands-free focus acquisition in the field.

Autofocus Support

Supports switching between autofocus and manual focus, giving shooters flexibility across different shooting scenarios.

Auto and Manual Focus

Designed to cover the full 35mm image circle, ensuring no vignetting on full frame Nikon DSLR bodies.

Full Frame Coverage

Adds minimal bulk and weight to an existing telephoto lens setup.

Lightweight 340g Build

Reduces the maximum aperture of the host lens by 2 stops, which is an important consideration for autofocus performance in low light.

2-Stop Aperture Reduction

The Mark III version incorporates optical and coating improvements over earlier TC-20E iterations for better contrast and flare resistance.

Third-Generation Design
