Key Features

1.4x Magnification

• Increased Focal Length: The TC-1401 extends the focal length of compatible lenses by 1.4x, allowing you to get closer to distant subjects. For example, a 200mm lens becomes a 280mm lens, providing greater reach for capturing detailed shots of distant wildlife or sporting events.

High-Quality Optics

• Advanced Lens Construction: The teleconverter is built with 7 elements in 5 groups, including one SLD (Special Low Dispersion) element that minimizes chromatic aberration and maintains high resolution and contrast throughout the image.
• Coating Technology: Multi-layer coating reduces flare and ghosting, ensuring that images remain sharp and vibrant even in challenging lighting conditions.

Durable and Weather-Resistant Design

• Rugged Construction: The TC-1401 is built to last, with a durable construction that can withstand the demands of professional use. The robust build quality ensures reliability in a variety of shooting environments.
• Dust and Splash-Proof: Designed for outdoor use, the teleconverter features a dust- and splash-proof construction that complements the weather-sealing of compatible Nikon F-mount lenses, allowing you to shoot confidently in adverse weather conditions.

Compatible with Select Sigma Lenses

• Optimized Performance: The TC-1401 is specifically designed to work seamlessly with select Sigma telephoto lenses for Nikon F-mount, ensuring that autofocus, image stabilization, and other lens features continue to function effectively. It is compatible with lenses from Sigma's Global Vision line, including the Sports and Contemporary series.

Additional Benefits

Maintain Autofocus and Image Quality

• Fast Autofocus: The TC-1401 is designed to maintain the autofocus performance of compatible lenses, ensuring quick and accurate focus even with the increased focal length. However, it’s important to note that autofocus performance may vary depending on the maximum aperture of the lens used.
• Minimal Light Loss: The teleconverter introduces a minimal loss of light, typically resulting in a one-stop reduction in maximum aperture. For example, an f/2.8 lens will function as an f/4 lens when paired with the TC-1401, while still delivering sharp and detailed images.
