Telephoto Extender 1.4x for Canon EF

This Canon EF 1.4X III Telephoto Extender multiplies the focal length of compatible Canon super telephoto lenses by 1.4x. It uses 7 elements in 3 groups to maintain optical quality with minimal chromatic aberration. A built-in microcomputer ensures full communication between camera body, lens and extender. The unit weighs 225 g and measures 72.0 mm by 27.2 mm.

Who this suits and who it does not

Photographers who own compatible Canon EF super telephoto lenses and need extra reach for wildlife or sports will benefit from the 1.4x magnification. The Fluorine coating resists soiling, smears and fingerprints during outdoor use. Dustproof and water resistant construction supports demanding field conditions. Buyers using non-Canon mounts, EF-S lenses or lenses not listed as compatible cannot attach or use this extender.

Deciding specification

The 1.4x magnification factor is the single figure that determines whether this extender matches the required focal length increase. Compatibility is limited to specific Canon EF super telephoto lenses, so the buyer must verify their lens model before purchase. No other specification overrides this requirement.
