My GGS's for the D7000 arrived yesterday and the D800's screens should be here early next week. I'll report back my impressions after I get them on. My biggest worry is getting them on straight....
Are those the glass screen shields?
Yes, they are. Apparently they're a combination of 6 layers with the optical glass layer in the middle. Some of the layers are a polymer to keep the glass from shattering into pieces while others claim to reduce glare and absorb impacts. At least that's what it says on the back of the packaging, for what its worth...
