Thank you for using Canon products.
We have determined that some EF 24-105mm f/4L IS II USM lenses exhibit an AF operation-related malfunction. The details of the phenomenon and Canon’s service policy are described below.

We would like to offer our sincere apologies to users who have been inconvenienced by this issue. Going forward, we will spare no effort in our quality management to make sure our customers can use our products with confidence.

Phenomenon
At the wide-angle end, focus is not achieved properly when a peripheral AF points are selected, regardless of the AF area selection mode.

Affected Lenses
If the first two digits in the serial number (see the image below) of your lens are ”48”, ”49”, ”50” or ”51”, then your lens MAY POSSIBLY be affected.

How to check if your lens is affected:
(1) Click the search button below to display the serial number input screen.

(2) Input your lens’ serial number (10 digits) and then click the [Submit] button.
* Please double check the serial number you entered before you click the [Submit] button.

(3) One of the following three messages will be displayed.
“Your lens is NOT an affected product”
“Your lens is an affected product”
“Invalid number”

*The list of affected lenses will be updated periodically in accordance with the handling status.
Market Support
If your lens is affected, support will be provided free-of-charge regardless of the warranty status. Please note that even if your lens is affected, inspection/repairs for any issue other than the above phenomenon will be handled as normal repairs.
