Superior
Image Quality

Versatile in every way

Adaptable Capabilities

Air Sphere Coating

Utilising the unique Air Sphere Coating (ASC), the RF800mm f/5.6L IS USM can suppress ghosting by reducing the reflectivity of light entering from a large angle of incidence and vertically. 

Super UD Lens

The RF800mm f/5.6L IS USM can produce superior image quality with minimal colour fringing from edge to edge of the frame using UD and Super UD Lens.

Fluorite Lens

The RF800mm f/5.6L IS USM produces high quality images with minimal chromatic aberration through the use of fluorite lenses. 

Optimised Lens Design

The elements are arranged in a way that significantly improves image quality. It also allows the lens design to be more compact and lightweight.  

Feature Packed

Convenience at its best

​​​​​​​

Extending Your Vision

Designed as a native RF mount lens, the RF800mm f/5.6L IS USM is compatible with the Extender RF 1.4x and Extender RF 2x.

Bolstering the lens's reach up to 1120mm and 1600mm, the RF800mm f/5.6L IS USM provides flexibility and convenience of shooting further with just one lens. 

Size & Weight Reduction 

The RF800mm f/5.6L IS USM is designed to be 29mm shorter and 1,360g lighter than its EF equivalent through new lens design by introducing innovative optics arrangements and a high-strength alloy lens barrel.

Image Stabilisation

The built-in Optical Image Stabilizer (Optical IS) provides image stabilisation of up to 4.5 shutter speed stops. The Optical IS enables shots previously not possible handheld, ensuring tack sharp images even when shooting in low-light. 

IS Modes

  1. IS Mode 1 for stationary subjects
  2. IS Mode 2 for panning shoots
  3. IS Mode 3 for subjects with unpredictable movement

High-Speed Shooting

High-speed continuous shooting of up to 30fps is supported when paired with compatible EOS R cameras using the electronic shutter.
