The Beauty


Lightweight and Compact Design

The RF100-400mm f/5.6-8 IS USM is physically smaller than an average 350ml tumbler, making it portable and compact enough to fit into a small bag or packed with other lenses without taking up much space. 

Weighing approximately 645g, the RF100-400mm f/5.6-8 IS USM is significantly smaller and a lot lighter compared to the EF100-400mm f/4.5-5.6L IS II USM that weighs 1,570g.



All-Round Zoom

The RF100-400mm f/5.6-8 IS USM has a large focal coverage from 100mm to 400mm.

Compatible with both Extender RF 1.4x and Extender RF 2x, the effective range can be increased to 560mm and 800mm respectively. 


0.41x Magnification

Through the RF mount design, the RF100-400mm f/5.6-8 IS USM has a short minimum focusing distance allowing it to achieve 0.41x magnification. 

Image Stabilisation

Natively, the RF100-400mm f/5.6-8 IS USM can achieve up to 5.5 stops image stabilisation. When paired with a compatible camera, the 5-axis In-Body Image Stabilizer (In-Body IS) and the In-Lens Optical Image Stabilizer (Optical IS) provide Coordinated Control Image Stabilisation (IS) capable of up to 6 stops of image stabilisation. 

Nano USM

This compact ultrasonic motor provides high-speed AF. The innovative AF actuator is suitable for high-precision micro-driving and delivers high performance even during movie recording and live-view shooting.

Lens Layout

The introduction of the RF mount has enabled the RF100-400mm f/5.6-8 IS USM to deliver high image quality in a lightweight and compact design. 

Super Spectra Coating

This special coating on the RF100-400mm f/5.6-8 IS USM reduces flaring and ghosting.

The coating also prevents contrast loss in a backlit scenario for a sharper and clearer image.

UD Lens

This lens uses a single Ultra Low Dispersion (UD) lens element with low refraction and low dispersion that reduces chromatic aberrations to deliver higher image quality.
