Overview

Extend your reach with the Canon Extender RF 1.4x, designed to seamlessly integrate with select Canon RF super-telephoto and telephoto zoom lenses. This high-performance teleconverter increases focal length by 1.4x while maintaining excellent image quality, autofocus performance, and full electronic communication between lens and camera body.

Engineered with high-refraction, low-dispersion glass elements, it minimizes chromatic aberration and preserves sharpness across the frame. Optimized lens coatings help reduce ghosting and flare, making it ideal for sports and wildlife photography where extended reach is essential.

Built for demanding conditions, the extender features dust- and water-resistant construction along with a heat shield exterior coating to help prevent overheating during prolonged outdoor use. Compact and lightweight, it’s a powerful addition to any RF super-telephoto setup.
