Air Sphere Coating

Utilising the unique Air Sphere Coating (ASC), RF400mm f/2.8L IS USM can suppress ghosting by reducing reflectivity of light entering from a large angle of incidence and vertically.

Super UD Lens

RF400mm f/2.8L IS USM consists of one Super UD Lens that produces images with minimal colour fringing from edge to edge of frame.

Fluorite Lens

Designed with 2 Fluorite Lenses, the RF400mm f/2.8L IS USM produces images with minimal chromatic aberrations.

Optimal Lens Design

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

Get Closer

With reduction of the minimum focusing distance, RF400mm f/2.8L IS USM is capable of achieving focus as close as 2.5m.

This provides the opportunity to be more creative and to capture more details of the subject.

Image Stabilisation

The built-in Optical Image Stabilizer provides image stabilisation of up to 5.5 shutter speed stops that enables shots previously not possible handheld, providing more convenience when shooting low-light.

2. IS Mode 2 for panning
3. IS Mode 3 for subjects with unpredictable movement
