The various Noname rear lid, which I have tried so far, are all quite scrap or never sit on all lenses really fixed permanently. Strangely, I previously had better experiences with one old Sigma and Tokina back cover, but you have to find first time. Anyway: The Nikon LF-4 is located just about anywhere perfect that it's a pleasure. Although the Nikon Prize may be covered - in this case, I put out more and then I like to permanently satisfied!
