To Users of RF70-200mm F2.8 L IS USM Lens
Thank you for using Canon products.
It has been confirmed that when using the RF70-200mm F2.8 L IS USM to perform AF shooting to capture a subject at close-range with the focus distance approximately set to the Tele-end (200mm), the image may become slightly front-focused.
New firmware (version 1.0.6) with improved focus accuracy is now available for download from your local canon website.
Note: The new firmware is for lenses equipped with firmware version 1.0.5 or earlier. The lens firmware version can be checked in the camera’s menu.
