Being one of the shortest and lightest 70-200 f/4 interchangeable lens in the world, the RF70-200mm f/4L IS USM provides high image quality throughout its focal length. Image stabilisation of up to 7.5 shutter stops* and
0.28x magnification makes this lens extremely adaptable to situations, so you can pursue your creative aspiration.
*with In-Body Image Stabilizer (IS) on a compatible camera. Up to 5 stops with Optical IS only.
Utilising the Air Sphere Coating (ASC) unique coating, RF70-200mm f/4L IS USM can suppress ghosting by reducing reflectivity of light entering from a large angle of incidence and vertically.
RF70-200mm f/4L IS USM is constructed with an arrangement of 4 UD lenses that are arranged effectively to produce images with minimal colour fringing from edge to edge of the frame.
The large diameter mount and short back focus design of Canon's RF mount have unleash new lens design possibility allowing image of exceptional quality to be crafted.
The two Nano USMs (Ultrasonic Motors) powers the RF70-200mm f/4L IS USM's autofocus (AF) capabilities, achieving fast accurate AF.
Each Nano USM works independently to control the focusing and floating lens groups: They prevent shifts in the focus position during zooming, and during close-up shooting, they conduct flexible lens position control which effectively prevents image quality from deteriorating.
The electronic floating focus control system within the RF70-200mm f/4L IS USM enables excellent control while reducing reliance on a mechanical system, contributing to a smaller lens design.
