The Nikon DR-6 provides an upright, unreversed image for right-angle viewing, 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 can be used with all Nikon SLR cameras that feature a rectangular viewing eyepiece, such as the D50, D70, D70s, D100, N80, N75, N70, N65, N60, N55, N50, N2000, N2020, N4040, N4004s, N5005, N6000, N6006, EM, FG, and Pronea 6i.
