The Block-Notes is a strut folding camera for 4.5×6 cm or 6.5×9 cm plates, made by Gaumont in Paris, from about 1904 (the smaller model) and about 1909 (the larger) until 1924.[1] It was available with a fixed-focus f/9 Hermagis anastigmat lens, or with faster lenses including a Tessar (on the example shown here, this is a Krauss-Zeiss lens, i.e. made by E. Krauss of Paris under licence from Zeiss; other similar examples have been seen;[2] however, one example sold at Westlicht is listed as having a CZJ Tessar).[3][4] Some cameras have a focusing mechanism (the knurled wheel on the rear body in the example illustrated); others are fixed-focus. Early Photography shows a fixed-focus example, which is, however, equipped with a ground-glass focusing screen, and two auxiliary close-up lenses.[5]
The lens of its Newton-type viewfinder is in a frame that slides along the lens board when the camera is folded (also covering the lens). The shutter is cocked by pulling the finder frame into its working position. A ground-glass screen can also be fitted. The example illustrated here has an optional plate magazine back fitted; single plate-holders can also be used.[3]
The shutter is a guillotine type, the blade moves under spring tension, with five instantaneous speeds, regulated pneumatically,[5] plus 'B'.
A stereo model, the Block-Notes Stereo was made from about 1904,[5] in sizes for 4.5×10.7 cm and 6×13 cm plates.[6][4]
