I was combing through a user manual and found a section about an eyepiece cover. So, who has implemented the 'eyepiece cover' into their workflow? Are there any other uses for the eyepiece cover? I read that it's uses include blocking light from entering the viewfinder, but has anyone used it while capturing video? Also, I don't use a neck strap. Admittedly, I used it twice, but removed it as it interferes with the way I handle a camera. I did not notice the eyepiece cover until I looked at a strap. I miss the darndest things!
