To Users of the EOS 650D Digital SLR Camera


Thank you for using Canon products.

It has been confirmed that the front rubber grips of some units of the Canon EOS 650D Digital SLR camera 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 650D units produced in certain lots between May 31st through June 27th, 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.

Caution on Use

The amount of zinc bis (N,N’-dimethyldithiocarbamate) detected during our testing was minimal. 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.
