Overview

Designed to extend a lens's focal length by a factor of 2x, the Canon EF 2.0X III Teleconverter slides into the workflow of select EF mount lenses. This renewed unit is built to pair with fixed focal length L-series lenses 135mm and above, including popular choices in the EF 70-200mm family and beyond. The result is added framing flexibility without changing position, a feature many wildlife, sports, and travel shooters appreciate under changing light and unpredictable action.

Key capabilities

  • 2.0x magnification factor for extended reach
  • 9 elements in 5 groups deliver compact, high-quality performance
  • Spectra coating helps reduce ghosting and flare for improved contrast
  • Fluorine coating keeps front surfaces cleaner and easier to wipe
  • Built-in microcomputer enables smooth communication among camera body, lens, and extender

Rugged design and field readiness

  • Designed for dustproof and water-resistant operation in challenging environments
  • Quality construction meets professional expectations when you are far from the studio

Practical use cases

In real-world shooting, this extender can help you frame distant wildlife, tighten sports compositions from the sidelines, or capture expansive landscapes with an intimate feel. The 2x boost pairs well with long telephotos, potentially reducing the need to physically move or crop heavily. While image quality depends on your chosen lens and shooting conditions, the combination of coatings and careful optical design aims to preserve contrast and color fidelity across a range of scenarios.

Compatibility and care notes

Compatibility is limited to select fixed focal length L-series lenses 135mm and up, and certain EF telephotos, as listed in the official specifications. To maintain performance, handle the extender with care, keep the contacts clean, and store it in a protective case when not in use. This unit is designed to be part of a pro-grade camera bag, ready to travel with your Canon system.
