Canon 1.4x III - 1896

Extending a lenses focal length by a factor of 1.4x, Extender EF 1.4X III incorporates phenomenal optical performance with minimal chromatic aberration and is a perfect complement to many of Canon super telephoto lenses. The Fluorine coating resists soiling, smears and fingerprints. Extender EF 1.4X III maintains high standards not only optically, but also in terms of rugged, dustproof and water resistant construction.

What our Experts Think

• Reliable teleconverter boost: The Canon 1.4× III teleconverter extends your lens reach by 40% (e.g., 100 mm → 140 mm), giving you extra framing power without buying a new lens.
• Maintains excellent communication: Preserves autofocus, exposure metering, and IS performance with compatible Canon EF lenses and bodies.
• Improved optics over previous generations: Canon’s III‑series design delivers better sharpness and contrast than older 1.4× teleconverters, minimizing image degradation.
• Compact & lightweight: Adds minimal bulk to your setup—easy to carry and use in the field.
• Professional‑grade build: Solid construction and reliable mount fit make this a dependable choice for travel, wildlife, sports, and nature shooters.
• Best with telephoto lenses: Works particularly well on long telephoto primes and zooms where extended reach yields the most impact.
• Aperture & light trade‑off: Expect a 1‑stop light loss after magnification (e.g., f/2.8 → f/4), so pairing with stable bodies or strong light conditions improves results.

Maintenance Tips

• Clean front and rear optics gently with microfiber cloth + air blower
• Always use front & rear caps to protect glass and prevent dust
• Store in a dry box or padded case with silica gel to avoid fungus
• Avoid touching optical surfaces directly
• Wipe mount contacts occasionally to maintain AF and lens communication
• Handle carefully—internal optics are precise and sensitive
• Keep away from extreme heat, humidity, and sudden temperature changes
• Check compatibility with lenses before mounting to ensure proper function
• Carry in padded compartment during transport to prevent impact damage
• Periodically inspect for dust, fungus, or mechanical issues
