In a statement describing the ‘phenomenon' on the £700 650D, Canon USA warns: ‘The front rubber grips on some EOS Rebel T4i (US camera name) units produced in certain lots during the 16-day period between May 31st through June 15th 2012 may turn white after a short period of time.
Canon UK has warned of a possible allergic reaction to skin and to consult a physician if medical symptoms develop. The firm has offered a free repair service, in a programme set to start on 17 July. Canon has not disclosed the number of cameras affected but stresses that only a 'limited number' are impacted. No-one has so far reported an allergic reaction, anywhere in the world, according to a UK spokesman.
