Designed for Mobility
At approximately 4.5 lbs. (2,050 g), the RF200-800mm F6.3-9 IS USM lens is relatively lightweight and compact for a super-telephoto 4x zoom lens with an 800mm telephoto end. This allows for comfortable handheld shooting and excellent mobility. The versatility of the 200-800mm zoom range also liberates you from carrying multiple lenses, making it very practical for various outdoor shooting situations.

High Image Quality
In order to maintain high image quality at any zoom range, the RF200-800mm F6.3-9 IS USM lens is equipped with an optimized optical design with a multi-group zooming configuration. Three Ultra-low Dispersion glass elements in its 17-element design ensure amazing color and sharpness. The lens takes advantage of the short back focus RF mount system to achieve both superb image quality and a lightweight, compact design.

Optical Image Stabilization — Up to 5.5 stops** of Shake Correction
For consistently sharp results, the RF200-800mm F6.3-9 IS USM features built-in optical Image Stabilization, providing enhanced shake reduction for up to 5.5 stops** of shake correction. The lens also supports Coordinated IS when paired with an EOS R-series camera that has In-Body Image Stabilization (IBIS). This means more reliable handheld performance and clearer detail in low-light situations, without having to increase the ISO or decrease the shutter speed.
** Based on CIPA (Camera & Imaging Products Association) standards. Testing performed using the EOS R camera. Coordinated IS only available with cameras equipped with IBIS and also provides 5.5 stops correction, using EOS R3 camera, in

Outstanding Operability
Several features are incorporated into the lens to enhance the operability for photographers. A Focus/Control Ring on the lens barrel can directly adjust numerous settings including shutter speed, aperture, exposure compensation and more — or act as a manual focus ring. Two conveniently located Lens Function Buttons allow you to program specific functions to occur at the press of either button, such as immediate access to Eye Detect AF, changes to exposure settings, and more***. The RF200-800mm F6.3-9 IS USM is also designed for smooth and balanced zoom operation, so the central balance of the lens doesn’t shift when the total length of the lens changes.
*** Lens Function button settings are performed in the camera’s “Customize Buttons” menu. Range of possible functions varies, depending upon camera model being used. Only one function can be applied at a time, and each button performs the same function.
