Canon Extender RF 2x

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- resistance 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 100% x 100% (horizontal x vertical) of the focal plane helping you to lock focus on your subjects more easily.
