This paper provides an account of the development of the multi‐lens aerial photographic cameras that were constructed in the UK for topographic mapping purposes under the auspices of the Air Survey Committee during the interwar period of the 1920s and 1930s. Three‐, five‐ and seven‐lens cameras were designed and built by the Royal Aircraft Establishment, Farnborough and by Barr & Stroud in Glasgow; these are described in some detail. The results of the mapping tests that were carried out with these cameras are also presented. Comparisons are made with the similar multi‐lens cameras that were constructed in the USA and Europe during the same period. The recent revival of multi‐lens aerial cameras with their oblique pointing lenses is also briefly discussed.
