The GuGo is a viewfinder camera for 2¼-inch square pictures on 120 film, made by Goldammer in Frankfurt in the 1950s. It was made in a range of specifications, very similar to the various models of the Goldeck. The example pictured at right here has a coated Steiner 75 mm f/2.9 lens, with front-element focusing and Pronto everset shutter, with speeds 1/25 - 1/200 second, plus 'B', mounted on a lens tube which telescopes into the body when not in use. The shutter release is on the shutter body, which also has a delayed-action control, and a PC socket; there is a 'cold' flash shoe on the top plate. Other examples resemble the specification of other Goldeck cameras: the camera pictured below left has an f/4.5 Steiner lens and a Vario shutter with speeds 1/25, 1/75 and 1/200 second, plus 'B', also flash-synchronised but without a delayed action. That at the bottom right has a Gugomat f/8 lens and Acro shutter, with speeds 1/25 and 1/75 second, plus 'B'.
