Canon RF 2x

These reliable and robust extenders match the performance of Canon RF lenses and deliver uncompromised imaging performance when used with compatible lenses. Both extenders feature lenses made of high-refractive-index glass with low dispersion. This counteracts field curvature and chromatic aberrations, ensuring excellent image quality. They also offer lens coatings and a three-layer combination lens to reduce ghosting. When used with the RF 100-500mm F4.5-7.1 L IS USM, the zoom range is limited to 300-500mm when the extender is attached.
