Upload & Sell: Off
It's my first time buying a screen protector. That's why I'm asking. I don't know what size or model I am looking for, because currently there is no screen protector that says it is for the 6D.
The new glass (GGS) LCD protectors are what I use on all of my cameras. They are inexpensive, the don't scratch easily and are easy to clean.
Personally, I would much rather replace one of these than the OEM one. I wouldn't mind a few small scratches on the LCD, but it really makes a big difference when you go to sell you camera.
