I have the viewfinder for my Samsung NX appointed me in 1000 because sunlight images are sometimes not visible on the display. He is also a help when you're Sucherkammeras usual and keep an eye on what is happening have muß..Er fits on the hot shoe of NX 1ooo. But it is a viewfinder for 24 mm.! What you see, is different from the actual image. But who can live with it, has a good optical viewfinder .. A small valent metal casing .. I give for solid packaging and fast delivery from Amazon four star. A small pocket is on board and protect the Aufsteckoptik.
