Polling the T4i owners
Nothing on my 650D. Will drop by the repair shop to have them replace the rubber.
My 70-200mm f/4.0L is another issue. Here the focus and zoom rings are almost completely white. Maybe I should ask Canon for a free upgrade to the IS model, or threaten to sell to a US lawyer. But I love the image quality of my 70-200. Pixel sharp on the T4i
