canon teleconverter

Canon teleconverters (extenders) are offered in two magnification factors: 1.4× and 2.0×.

Built-in microprocessors maintain communication between camera and lens so autofocus, exposure metering, and image stabilization continue to operate when a teleconverter is attached. Actual performance (speed, accuracy, or availability of functions) can vary depending on the specific camera and lens used.

The 1.4× extender uses seven elements in three groups; the 2.0× extender uses nine elements in five groups. Both include Super Spectra/Spectra coatings and a fluorine coating to help reduce ghosting, flare, smudges, and fingerprints.

The 1.4× extender produces a 1-stop light loss.

Package contents typically include the extender, extender cap, rear lens dust cap, lens case, instruction manual, and warranty.

Teleconverters are ideal when you need extra reach to capture distant subjects, such as in sports, wildlife, nature, and news photography.

They feature weather‑resistant construction with dust and water resistance, and fluorine‑coated front and rear elements to repel water, dust, and fingerprints for easier cleaning.
