Canon RF 70-200mm f / 4L IS USM
Popular for its reach and flexibility, the Canon RF 70-200mm f / 4L IS USM is a new take on this well-regarded focal length, with an impressively sleek and lightweight form factor perfect for your full-frame mirrorless cameras. The constant maximum aperture of f / 4 strikes a balance between being bright enough to shoot in available light while also contributing to the especially portable, hand-held design. Complementing this is a suitable Optical Image Stabilizer, which compensates for up to 5 stops of camera shake, or an impressive 7.5 stops of motion correction when combined with an EOS R-type body with IBIS.
Optically, this lens incorporates four UD elements, which suppress a variety of aberrations throughout the zoom range for high clarity, and an Air Sphere coating is also featured to reduce flare and ghosting. Balancing the distinguished optical system is a Dual Nano USM focusing system, offering fast and near-silent autofocus performance with full-time manual focus override. Additionally, this 70-200mm is weather sealed and has a fluorine coating to protect the front and rear elements.
The versatile telephoto zoom lens is designed for use with full-frame Canon RF-mount mirrorless cameras.
The constant maximum aperture of f / 4 provides 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 minimize chromatic aberrations and color fringing to provide greater clarity and color accuracy.
An air sphere coating (ASC) has been applied to the lens elements to reduce flare and backlight ghosting to maintain light transmission and high contrast in bright lighting conditions.
An Optical Image Stabilizer helps minimize the appearance of camera shake by 5 stops to allow better work in low light conditions and at slower shutter speeds. Additionally, when working with select cameras, up to 7.5 stabilization stops may be available with the Coordinated Optical Image Stabilizer and In-Body Image Stabilization.
The Dual Nano USM system uses a ring-type USM mechanism and an STM mechanism to realize fast and precise focusing that is also smooth and near-silent to suit photo and video applications. This focus system also allows full-time manual focus control when working in one-shot AF mode.
The configurable control ring can be used to adjust a variety of exposure settings, including aperture, ISO, and exposure compensation.
A protective coating of fluorine has been applied to the front and rear element to resist fingerprints and smudges and to facilitate cleaning of these elements.
As a member of the esteemed L-series, this lens has a weather-resistant design that protects against dust and moisture to enable use in harsh conditions.
