I just bought the Nikon 80-200 F2.8 AF-D mrgreen::mrgreen::mrgreen::mrgreen, however I have not purchased any kind of protection for it. I am planning on buying the hood, however I'm debating if I should invest in a good UV filter. From what I have heard, Canon's L glass's front element is purely protective, and damage can be repaired for ~$100. Is this true with the 80-200? Or will the repair cost be much more significant should something unfortunate happen to the front element?
