Extender RF 2x

Extends a super-telephoto lens’ focal length by 2x, so that an 800mm focal length, for example, becomes 1600mm. The extra reach makes it possible to get larger close-ups with the original camera resolution.

  • Dust and drip resistance design with white heat-shield coating
  • Supports high-precision AF
  • Excellent Flare and Ghosting Reduction

High Image Quality

A large aperture lens placed near the image sensor, the use of high-refractive, low-dispersion glass, and three cemented lenses that minimise air contact surface suppress field curvature, lens aberration and flare and ghosting, hence optimising corner-to-corner image quality.

Strength & Reliability

The lens features a vibration- and impact-resistant structure with a dust- and drip-resistant design, ready to withstand nature, motorsports, and other harsh professional and advanced shooting scenes.

Supporting heavy lenses is all in a day’s work for its robust, durable body.

AF Support

Shooting at super-long focal lengths means a shallower depth-of-field, which can make focusing tricky. On the Extender RF 2x, built-in microprocessors communicate with the lens, achieving high-precision AF over an area as large as up to 80% x 80% (horizontal x vertical) of the focal plane* helping you to lock focus on your subjects more easily. 

*With EOS R5 or R6 on the RF100-500mm f/4.5-7.1L IS USM. Actual AF area depends on the lens, extender, and camera body.
