Several clam-shell shaped camera designs were patented and had appeared in the late 1890s and early 1900s including Houghton's Triad and Butcher's So-Li-To around 1898 and the Adam's Natti was another variant on this design. It was a reworked and updated version of Adam's 1892 Vesta design . An announcement in 1899 stated that the Natti would be ready 'early in 1899'. It was succeeded by 1905 by the improved Nattia.

The Natti was described by Adam's as: 'An extremely small and neat folding camera, capable of being carried in a coat pocket. Is absolutely self-contained, lens, finder, shutter, level, rising front, camera and eight plates or fourteen flat films, all being self-contained'. Three models with a Bausch and Lomb Rapid Rectilinear f/7.7, Ross Symmetrical f/8 and Zeiss Series VIIa No. 4 f/6.3 lens were available at £7 10 0, £10 17 6 and £15 15 0 respectively.
