From Canon:
Thank you for using Canon products.
In rare cases, the AF function on some PowerShot ELPH 180 compact digital cameras may not operate properly and focus may not be achieved. Customer support for this phenomenon is described below.
We take great pride in the quality and performance of our products. We offer our sincerest apologies to any customers who may be inconvenienced.
Phenomenon
In rare cases, when shooting still images or movies with the PowerShot ELPH 180 compact digital camera, the AF function on the camera does not operate properly, and focus is not achieved in the captured image or movie, even if the AF frame is displayed.
Affected Products
Only some PowerShot ELPH 180 compact digital cameras are affected by this phenomenon.
The phenomenon may occur in cameras whose first two digits in its serial number are “11”, “12” ,“21”,“22”,”23” or”24”. Examples of serial numbers for cameras that may be affected: “11xxxxxxxxxx” , “12xxxxxxxxx”, “21xxxxxxxxxx”, “22xxxxxxxxxx”, “23xxxxxxxxxx”, “24xxxxxxxxxxx” (‘x’ can be any number).
If the camera has a black marking on the inside of the battery cover, as shown in the image below, this indicates that your camera has been checked and the issue has been corrected.
If you have not already done so, please register your PowerShot ELPH 180. By registering, we will be able to notify you via email about future service upgrades.
