Canon 4114C002 EXT RF2X(N) Lens Extender

The Canon Extender RF 2x (model 4114C002) is a teleconverter designed to double the focal length of compatible Canon RF-mount telephoto lenses, making it a compact alternative to carrying additional long lenses. Built with advanced optical elements and optimized coatings, it is engineered to preserve image quality while minimizing chromatic aberration, ghosting, and flare. The extender maintains full electronic communication between the lens and camera body, supporting autofocus, image stabilization, and EXIF data transmission.

Constructed with dust and water resistance, the RF 2x Extender is built for field use in demanding environments—a critical feature for wildlife and sports photographers who often shoot in rain, dust, or extreme temperatures. The exterior also incorporates Canon's heat-shield coating to reduce heat buildup during prolonged outdoor sessions. At 1.5 pounds, it adds reach without dramatically increasing the weight of your kit. The trade-off is a two-stop reduction in maximum aperture, so pairing it with fast telephoto glass like an f/2.8 lens (which becomes an effective f/5.6) helps maintain usable aperture and autofocus performance.
