Canon has warned that a manufacturing defect in its 650D models may cause an allergic reaction to users.
According to Canon’s warning, the amount 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.”
The white substance is apparently known as ‘zinc bis’ and can cause rashes, sneezing and red eyes.
Owners of a 650D, or Rebel T4i as it’s known in some markets, can find out if their device is affected by entering its serial number here.
“We will provide a free repair service for all cameras identified as having been affected by this phenomenon. This free repair service will begin on 17 July 2012,” read Canon’s statement.
