This is not the Rollop by Lipca.

The Roll-Op are German folding cameras using 120 film, sold by Plaubel in the 1930s. They were rebadged Balda cameras, some of which incorporated advanced features added by Plaubel.

Viewfinder-only models Edit

Balda folding cameras were sold by Plaubel from 1933 as the Fix Focus. The smaller model, for 4.5×6cm exposures, was a name variant of the Baldax (for #0 shutter size), and the larger one, for 6×9cm exposures, was a rebadged Balda Fixfocus.[1]

In 1934, the Fix Focus models were replaced by the Roll-Op.[2] The 4.5×6cm model was still a rebadged Baldax, but the larger model was a 6×9cm and 4.5×6cm dual-format folding camera, name variant of the Balda Gloria, sometimes with a different Pracht viewfinder.[2]

Rangefinder model Edit

The rangefinder model was released as the Roll-Op II, but it was eventually sold as Roll-Op in short — sometimes spelled Rollop. Its main difference from the Baldax is the addition of a coupled rangefinder, separate from the viewfinder. This rangefinder unit is the same as mounted on the Makina. There is also an automatic exposure counter, the position of the first frame being set via a red window. This device is similar to that mounted on Plaubel rollfilm holders. It was copied by Chiyoda for the Auto Semi Minolta.

The Roll-Op II exists in two versions, for 4.5×6cm exposures or 6×6cm exposures. They differ by the finder size, the exposure counter and the red windows. The 6×6 model has a single red window in the middle of the back, protected by a pivoting cover mounted in a round plate, whereas the 4.5×6 model has two red windows at the top of the back, protected by a rectangular sliding cover.

The lens is a Plaubel Anticomar 7.5cm f/2.8 with unit focusing on both versions. The shutter is either a Compur to 1/250 or a Compur-Rapid to 1/400.
