Canon EF 2X III Extender Teleconverter 2.0x Magnification for Compatible Canon EF Lenses, 7-Element Optics (White) - New

Professional Focal Length Extension

The Canon EF 2X III Extender is a precision optical accessory that doubles the focal length of compatible Canon EF lenses, transforming a 300mm lens into a 600mm powerhouse. Featuring a redesigned 7-element, 5-group optical formula, this teleconverter delivers optical performance on par with Canon's finest super telephoto lenses. Ideal for wildlife, sports, and nature photography where getting physically closer isn't possible, it maintains full communication between camera body and lens through its built-in microcomputer.

Advanced Optical Engineering

Careful lens placement and advanced coatings minimize ghosting, flare, and chromatic aberration across the frame. The new Fluorine coating on exterior elements repels soiling, smears, and fingerprints, making maintenance simple in challenging field conditions. At 2.8 inches in diameter and 2.3 inches long, weighing just 9.3 ounces, this extender adds minimal bulk to your kit while delivering maximum reach. The 2.0x magnification reduces effective aperture by two stops, so lenses with f/2.8 or faster maximum aperture maintain autofocus capability with any EOS body.

Professional-Grade Durability

Built to match the rugged construction of Canon's professional lens lineup, the EF 2X III Extender features dustproof and water-resistant seals that protect internal elements in adverse conditions. The weather-resistant design ensures reliable performance whether you're shooting in light rain, dusty environments, or humid climates. Image Stabilization technology is fully maintained, allowing you to handhold longer focal lengths with confidence and capture sharp images even at extreme telephoto distances.
