FAQ: Important announcement regarding EOS 650D


The details below have been revised as of 3rd August 2012.

The database has been updated to include additional serial numbers. Customers who previously checked the serial number of their camera on our website and received an “unaffected” message are asked to please recheck the serial number.

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. 

The front rubber grips of some EOS 650D units produced between May 31st and June 27th 2012 may turn white after a short period of time. After investigation and analysis with the rubber manufacturer, we have determined that zinc bis (N,N’-dimethyldithiocarbamate) is the substance that causes the rubber surfaces to turn white (see surfaces in image below).

The amount of this substance that has been detected on any individual unit is minimal but in rare cases, depending on individual sensitivity, contact with this substance may cause an allergic skin reaction.

Further Details

About Zinc bis (N,N’-dimethyldithiocarbamate):

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.

About any possible reaction:

Although only a minimal amount of zinc bis (N,N’-dimethyldithiocarbamate) can be detected on any one single unit, when this substance is in contact with the skin, in rare cases and depending on one’s health and physical conditions, allergic skin reactions may develop. In addition, if eyes are rubbed with hands adhered with this 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 rubber parts that have turned white.

Allergic skin reactions:

In the event that the substance in question is absorbed into the body through skin contact, it may invoke a sensitization response. If a sensitization response is induced, allergic skin reactions occur where the body may then overreacts to contact with the foreign substance. Please note that the occurrence of an allergic skin reaction on contact with this substance depends on length and type of contact with the substance, individual health and physical conditions, and individual skin sensitivity. Not everyone will be affected by allergic symptoms and the severity of any such allergic reaction will depend entirely on the individual.

If medical symptoms develop, please consult your physician.
