The precious red ring around my 24-105 L has split. I don't know how it happened. Typically, I treat my equipment very carefully.
The red ring will slip off easily now. I'm sure Canon would replace it, but it just doesn't seem to be worth the shipping or whatever cost it might entail.
I guess I'll have to "tell" people I'm using an L lens, instead of letting the lens speak for itself. Drat! [:'(]
