I am looking for a durable screen protector for my OM-D 5. I do not use the touch ability of the screen, so that is not important. I would prefer something like Nikon uses on the screen so it is well protected in the bag. Even a plastic opaque cover would be fine if it snaps tightly on the screen, I mainly use the viewfinder anyway. I find the small thin protectors a bit to thin, that´s why I want something more sturdy. Any ideas?
