Recent Canon EF 50mm f/1.4 USM Recall

Posted on September 12, 2017 by Mason Bauer

Do you own a Canon EF 50mm f/1.4 USM lens? If so, your lens might be affected by a focusing issue.

Don't panic. We have all of the information you need to know about checking your product and contacting Canon's customer service.

The Issue

While in AF or MF mode, when the lens focuses from infinity to close-up, the focusing operation will often get stuck at the position marked by the red circle below.

Before you grab your 50mm lens and start messing with the focusing system to see if it is affected, there are only a certain number of products that are defective.

How to Check Your Product

If you take a look at the bottom of the lens where the mounting plate is, you will see a series of numbers. These numbers are the serial number for your specific lens (see image below). The only thing you have to look for are the first four digits of the serial number (marked by red box). If the first four numbers are “4918”, “5018”, “5118”,  “5119”, “5218”, “5219”, “5318”, “5319”, “5418”,  or “5419" then your lens may possibly be affected by the issue. If your product has matching digits, you should contact the Canon service department, and they will walk you through the process of sending your lens in for repair.

Upon sending the item in, it will be inspected, and if necessary repaired free of charge.
