Canon reissues service notice for 24-105mm f/4L IS II

Two weeks ago to the day, we told you about an interesting service advisory which popped up on the website of Canon Philippines. A short while after our article went live, the update vanished and a few days later we received a confirmation that it had accidentally been released early. And now, it's back! (And not just on a random Canon website, but on the company's US and Canadian websites. (You can see it on the Canon USA site here, if you want, or read on for the nutshell view.)

So what's the issue behind this service advisory? Well, just as in the original notice on the Canon Philippines site, Canon USA's service notice states that with some lenses, a focus lock cannot be achieved with the peripheral AF points participating, regardless of AF area selection mode.

It's important to note that not all Canon 24-105mm f/4 L IS II USM lenses are affected. As in the original advisory, Canon USA notes that if your serial number starts with 48, 49, 50 or 51, then you may possibly be affected. (But it's not a sure thing; to find out for certain you'll want to enter your full serial number in the form located here.)

Canon USA isn't yet accepting lenses with the issue for repair, but notes that it plans to do so and that it will inform users "[as] soon as preparations have been completed". Rest assured we'll be doing the same, so watch this space for more on this story!
