RF 1.4x Teleconverter Bundle

This Canon Extender RF 1.4x multiplies the focal length of compatible RF-mount lenses by 1.4x while preserving metering, autofocus, image stabilisation and Exif data transfer. The bundle adds a lens pouch, lens cap keeper and cleaning kit for protection and maintenance. It is built for mirrorless camera users who need extra reach without losing electronic communication.

Extends Select RF Lenses

The converter works with the RF 100-400mm f/5.6-8 IS USM, RF 100-500mm f/4.5-7.1L IS USM within the 300-500mm range, RF 400mm f/2.8L IS USM, RF 600mm f/11 IS STM, RF 800mm f/11 IS STM and RF 600mm f/4L IS USM. Photographers using other RF lenses or EF-mount glass cannot attach this extender, so the upgrade is only worthwhile when the owned lens appears on the supported list.

Simple Mount With Weather Seals

The extender locks onto the camera and lens like a standard RF optic; no firmware step or adapter is required. Dust and water resistance plus a heat-shield exterior help reliability in harsh conditions, though forgetting to clean the rear element before mounting can introduce spots, and using the RF 100-500mm outside its 300-500mm window will prevent proper operation.
