The Nikon DR-6 Rectangular Right Angle Viewfinder provides an upright, unreversed image for right-angle viewing, which is very convenient for waist-level or low-angle photography. Individual eyesight adjustment is possible with the built-in diopter, and the reproduction ratio can be set to 1:1 or 1:2. This version is designed to be mounted on SLR cameras featuring a rectangular viewfinder with a slip-on accessory slot.
