Cleaning & Maintenance:

The Canon RF Extender 1.4x boasts a massive reach and combined with high-resolution RF lenses allows professional photographers to shoot distant subjects without any compromise in image quality.

Please Note: The Canon RF Extender 1.4x is only compatible with specific Canon RF lenses. It may also only have limited functionality with some of those lenses. Please see the compatibility table to determine which lenses are usable and the level of functionality possible.

Superb image quality

The RF Extender 1.4x utilises both the lens's built-in IS and the high-precision EOS R's Dual Pixel CMOS AF to expand the telephoto range by 1.4x and maximise the performance of the master lens.

Durable with dust and drip-proof structure

The RF Extender 1.4x features a durable vibration and impact resistant structure which makes it reliable in rough shooting conditions. It is also dust and drip-proof which allows you to photograph in harsh shooting scenes like motorsports or wildlife photography.
