Five weeks ago, I got my new camera, a Canon 40 D. This weekend, I discovered there was dust and something looking like a curly hair on the viewfinder. This morning, I went back to the store where I bought it and their reaction was rather unsatisfying They told me this was normal and that they can send the camera back to Canon but that it will take ages to have it back. I should just learn to live with it. I told them that one of the reasons I choose the 40 D was that it was supposed to be better sealed than the 400 D model but that didn't help either.
Does anybody know if I can clean the matte glass of the viewfinder myself without too much risk?
