I can't find any cheap D7100 LCD loupe for video use. I'm talking about ebay, around $12-$14 available for most DSLRs. Anybody seen one for D7100? Or maybe one from another DSLR would fit? I think most won't, because the LCS is 3.2" instead of 3.0" on D7000, and I'm not sure about its location. Does the one from D7000 has extra space around the edges so it would fit?
