Expand the telephoto range

With the high resolution of the RF lenses, the RF Extender 2x can easily perform super-telephoto shooting by extending the focal length by 2x. High-precision AF using the EOS R's Dual Pixel CMOS AF and the lens's built-in IS can also be utilised, making full use of the performance of the master lens to expand the telephoto range.

High image quality

The RF Extender 2x achieves both high image quality and a smaller size with an optical design that utilises the large diameter mount and short back focus unique to the RF mounts.

Reliable design suitable for even harsh shooting conditions

The durable vibration and impact resistant structure, and dust and drip-proof design makes it safe to use in even harsh shooting scenes such as nature photography and motor sports.
