To Users of the PowerShot SX50 HS Compact Digital Camera.
Thank you for using Canon products.
The rubber of the viewfinder of some units of the Canon PowerShot SX50 HS compact digital camera may change colour (turn white) after a short period of time. 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
The rubber section of the viewfinder of some PowerShot SX50 HS digital compact cameras produced in certain lots from September 1 through November 15, 2013 may turn white after a short period of time. We have determined after inquiry with the rubber manufacturer and internal analysis that the white substance is zinc bis (N,N’- dimethyldithiocarbamate).
Zinc bis is not used in the production of this product. The reason for the depositing of this material was the use of an improper rubber accelerator by the manufacturer of the rubber viewfinder. As a result the rubber section of the viewfinder may turn white due to a chemical reaction with the rubber accelerator and other substances. High temperature and high humidity may contribute to this condition. Zinc bis (N,N’- dimethyldithiocarbamate), which becomes deposited on the rubber surface, is created as a result of this chemical reaction.
Affected products
Only a small fraction of the PowerShot SX50 HS compact digital cameras – the ones containing the improper rubber accelerator – are 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 serial numbers of cameras that may be affected) “69xxx1xxxxxx”, “70xxx1xxxxxx”, “71xxx1xxxxxx” (‘x’ can be any number)
Caution on use
The amount of zinc bis (N,N’-dimethyldithiocarbamate) deposited on the affected units is minimal. However, depending on one’s health and physical condition, in rare cases it is possible for zinc bis to cause allergic reactions, such as a rash, when it comes in contact with the skin of sensitive persons. In addition, if the eyes make contact with the substance, symptoms, such as red eyes may develop.
As a precautionary measure, thoroughly wash your hands and rinse your eyes with water if they have come into contact with the rubber part of a viewfinder that has turned white. If any medical symptoms develop, please consult your physician immediately.
Support
Affected cameras that exhibit this phenomenon will be inspected and the rubber section of the viewfinder will be replaced free of charge. If you own one of the affected cameras please contact our Customer Support Centre. Our free viewfinder replacement service commences from Monday 6 January 2014.
