Have the part now get by mail (shipping faster!) And am satisfied on the whole. Since I but on my DSLR Rig Matte Box with use etc. I wanted to buy a Viewfinder, which stops at an adhesive film on the display me. The saw on the product photo also so, because you can not see anything there from the attachment which is screwed at the camera. But qualitatively it is all right, the magnet holder is strong enough and you need not to be afraid to fall in front. The lens is a nice size and the display focus entirely on the image. I do not know the difference to more expensive View finders, but the picture is somewhat distorted. Who something is important, this should be keep away. But I am on the whole satisfied with the part.
