Canon RF 70-200mm f/4 L IS USM: Lightweight and Versatile Telephoto Zoom Lens for Canon RF-Mount Mirrorless Cameras

The Canon RF 70-200mm f/4 L IS USM is a popular lens known for its reach and flexibility. Designed for full-frame mirrorless cameras, it offers a sleek and lightweight form factor, making it an ideal companion for photographers on the go. With a constant f/4 maximum aperture, this lens strikes a balance between brightness for available light shooting and a portable, handholdable design. The built-in Optical Image Stabilizer compensates for up to 5 stops of camera shake, or an impressive 7.5 stops of shake correction when used with an EOS R-type body with IBIS (In-Body Image Stabilization).

Key Features:
– Versatile telephoto zoom lens designed for full-frame Canon RF-mount mirrorless cameras.
– Constant f/4 maximum aperture ensures consistent performance throughout the zoom range and contributes to the lightweight and compact form factor.
– Four UD (Ultra-Low Dispersion) elements minimize chromatic aberrations and color fringing, resulting in enhanced clarity and color accuracy.
– Air Sphere Coating (ASC) reduces flare and ghosting, maintaining light transmission and high contrast even in strong lighting conditions.
– Optical Image Stabilizer minimizes camera shake by 5 stops, enabling low-light shooting and slower shutter speeds. With compatible cameras, the Coordinated Optical Image Stabilizer and In-Body Image Stabilizer can provide up to 7.5 stops of stabilization.
– Dual Nano USM system combines a ring-type USM and an STM mechanism for fast, accurate, and nearly silent autofocus performance. Full-time manual focus control is available in one-shot AF mode.
– Configurable Control Ring allows adjustment of various exposure settings, including aperture, ISO, and exposure compensation.
– Protective fluorine coating on the front and rear elements resists fingerprints and smudges, making cleaning easier.
– Weather-resistant design protects against dust and moisture, enabling use in challenging conditions.

Firmware Update 1.1.0 (December 2021):
– Adds electronic full-time manual focus function for constant manual focus adjustment in both one-shot AF and servo AF modes when used with EOS R5, EOS R6, and EOS R3 cameras.
– Improves blurring of the background during slow panning when IS (Image Stabilization) mode is set to Mode 2 or Mode 3.

Please note that firmware update 1.1.0 added these improvements. Check the firmware version in your camera menu as instructed in the manual.
