The rubber of the viewfinder of some units of the Canon PowerShot SX50 HS compact digital camera may change color (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.
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.

The front rubber grips of some units of the Canon EOS REBEL T4i Digital SLR camera (EOS 650D/EOS Kiss X6i overseas models) may change color (turn white) after a short period of time. Customer support for this phenomenon is described below.
Canon continuously strives to provide our customers with high quality, reliable products that can be used with confidence. We offer our sincerest apologies to any customers who may be inconvenienced.
The front rubber grips of some EOS REBEL T4i units produced in certain lots during the sixteen-day period between May 31st through June 15th, 2012 may turn white after a short period of time. We have determined after inquiry with the rubber manufacturer and analysis, that the substance zinc bis (N,N’-dimethyldithiocarbamate) is what causes the rubber surface to turn white.
Zinc bis is not used in the production of this product. However, the quantity of rubber accelerator used in the affected production lots was slightly higher than usual. As a result the rubber grips 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.
Some EOS Rebel T4i digital SLR cameras produced from May 31 through June 15 may be affected.

Caution on Use
The amount of zinc bis (N,N’-dimethyldithiocarbamate) detected during our testing was minimal. While Canon has not received any reports of injury or allergic reactions, 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 eyes are rubbed after contact with the substance, symptoms, such as red eyes, may develop.
As a precautionary measure, thoroughly wash your hands with water if they have come in contact with the rubber grips that have turned white. (If any medical symptoms develop, please consult your physician immediately.)
*Please note that the occurrence of allergic skin reactions depend on the target substance, length of contact with the target substance, one’s health and physical conditions, and sensitivity of one’s skin structure, and not everyone will be affected by allergic symptoms.
Preparations are underway to provide free repair service for affected cameras by replacement of the rubber grips. Once this repair service is available (ETA of mid July 2012), we will post an update on our web site and also notify registered users via email. Please register your EOS Rebel T4i, so that we can inform you via email when the free repair service will commence.
