For 7 out of 8 years the LCD on my 1D Mk II has lived with an annoying scrape seemingly etched into what was supposed to be a very scratch-resistant LCD. One of the nicest things about my new 5d MkIII is that there are no scratches on the LCD yet, and I would like to keep it that way. I know they are supposed to be almost indestructible, but I think I should have a protector for it.
I have not found any that are the correct size, other than one that relies on adhesive, which I do not want to use. What have people found for their 5D3III LCD's?
