To Users of the PowerShot SX50 HS Compact Digital Camera

Thank you for using Canon products.

It has been confirmed that the rubber of the viewfinder of some units of the PowerShot SX50 HS compact digital camera may change color (turn white) after a short period of time. Customer support for this phenomenon is described in the following Market Support.

Canon continuously strives to provide our customers with high quality, reliable products that can be used with confidence. We offer our sincerest apologies to all customers who may be inconvenienced by the phenomenon.

Free Repairs for this matter is stopped from January 2015


The rubber section of the viewfinder on some PowerShot SX50 HS digital compact cameras which were produced in certain lots from September through November 2013 may turn white after a short period of time. Following analysis of the rubber, we have determined that the presence of the substance zinc bis (N,N'- dimethyldithiocarbamate) is the cause of this color change.

The reason for the depositing of this material is the mistaken use of rubber accelerator in the manufacturing process of the parts. This causes a chemical reaction with other substances in the rubber when placed under conditions of high temperature and high humidity.

Affected Products

Some units of the PowerShot SX50 HS compact digital camera were affected by this phenomenon.

This phenomenon may occur in cameras of which the first and second digits from the left in the serial number are "69", "70", or "71" and the sixth digit of the serial number is "1". (Example of camera serial numbers that may be affected) "69xxx1xxxxxx", "70xxx1xxxxxx", "71xxx1xxxxxx" ('x' can be any number)

Market Support

Canon will offer a free replacement of the viewfinder rubber for affected units at service centers, regardless of their Canon warranty status.

Our free replacement service will begin on 10th January 2014.

Caution on use

The amount of zinc bis (N,N'-dimethyldithiocarbamate) deposited from one affected unit is minimal, however depending on one's health and physical condition, in rare cases when this substance comes into contact with skin, allergic skin reactions* may develop. In addition, if the eyes are rubbed after contact with the substance, symptoms, such as red eyes may develop.

As a precautionary measure, thoroughly wash any areas that have come into contact with rubber parts that have turned white with water. If any medical symptoms develop, please consult your physician immediately

Please note that the occurrence of allergic skin reactions depends on the length of contact with the substance, one's health and physical condition and the sensitivity of one's skin. Not everyone will be affected by allergic symptoms. At present, we have received no reports of users being affected by allergic symptoms in connection with this issue.
