Canon RF 70-200mm f/4L IS USM Lens

Versatile telephoto zoom lens is designed for use with full-frame Canon RF-mount mirrorless cameras.

Constant f/4 maximum aperture affords consistent performance throughout the zoom range and also contributes to the relatively lightweight design and compact form factor.

Four UD (Ultra-Low Dispersion) elements help to minimise chromatic aberrations and colour fringing in order to provide greater clarity and colour accuracy.

An Air Sphere Coating (ASC) has been applied to lens elements to reduce backlit flaring and ghosting for maintained light transmission and high contrast in strong lighting conditions.

An Optical Image Stabiliser helps to minimise the appearance of camera shake by 5 stops to better enable working in low-light conditions and with slower shutter speeds. Also, when working with select cameras, up to 7.5 stops of stabilisation may be available with the Coordinated Optical Image Stabiliser and In-Body Image Stabiliser.

Dual Nano USM system utilises both a ring type USM and an STM mechanism to realise quick and accurate focusing that is also smooth and nearly silent to suit both photography and video applications. This focusing system also affords full-time manual focus control when working in the one-shot AF mode.

Configurable Control Ring can be used to adjust a variety of exposure settings, including aperture, ISO, and exposure compensation.

Protective fluorine coating has been applied to the front and rear element to resist fingerprints and smudges and to make cleaning these elements significantly easier.

As a member of the esteemed L-series, this lens has a weather-resistant design that protects against dust and moisture to enable its use in inclement conditions.
