- Product Details
Notes: Not all Canon EF lenses are compatible with this extender. For a list, see this chart. Also note that as of this writing, AF is not retained when pairing this teleconverter with the Canon EF 100-400mm f/4.5-5.6L IS II USM Lens.
The Canon Extender EF 1.4x III mounts between your camera body and lens in order to give your lens more reach through magnification. It features a built-in microcomputer for seamless communication among camera body, lens and extender. Note that this extender reduces your maximum aperture by 1 stop. It is recommended that you attach the extender to your lens and then attach the pair to your camera body. Extenders allow photographers to shoot from greater distances without having to resort to using larger and longer lenses. They are compatible with both full frame and crop frame sensor cameras and they are ideal for sports and wildlife.
