I just installed a new plastic gg with grid (mat side towards lens) then the fresnel (w/grooves toward lens) - according to the YouTube Video I watched I like how bright it is, but the annoying thing about it is the light coming through the camera from the lens. It looks like a giant full moon and makes it very hard to focus. Other than that, I like it. Is that because it's a cheaper brand? I got it on ebay several years ago and the sticker says Global Screen. The man's name I think is Mr. Wang. Any thoughts would be greatly appreciated!
