The Nikon DR-5 is a right-angle Viewing Attachment can be attached to the finder of Nikon SLR cameras. With this attachment, the viewfinder image is viewed at right angles (via the built-in roof prism) to the camera's optical axis - a feature that is very convenient when shooting from low (or high) viewpoints, or when normal finder viewing is proving difficult, as can be the case in close-up work or photomicrography.
It allows for setting the reproduction ratio to either 1:1 or 1:2 and an adapter ring is required for certain specific cameras.
Diopter adjustment: 1:1 is -8.0 to +3.8m-1. 1:2 is -5.0 to +6.0m-1.
Dimensions: 48 x 81.5 x 62mm (1.9 x 3.2 x 2.4 in.).
Weight: 90g (3.17oz).
Compatible with: Nikon D2H, D2Hs, D2X, D2Xs, D3, D3X, D700.
