Canon issues allergy alert over camera grip

ERJ staff report (DS)

Tokyo - Canon has issued an allergy advisory after it found excessive amounts of rubber accelerator in the hand grips used on some of its products.

In a statement, Canon said, “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.”

It added, “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, 2012 may be affected.
