Canon L EF 200-400mm IS USM Extender 1.4x 200-400mm
The built-in 1.4x extender instantly shifts this 200-400mm f/4L lens to a 280-560mm f/5.6, offering seamless focal length flexibility without swapping teleconverters. Its constant f/4 aperture and fluorite optics deliver sharpness and contrast that hold up even with the extender engaged.
