The A-1 camera system consisted of two 24-inch K-38 framing cameras. One was mounted vertically and photographed a $ 1 7. 2^{\circ} $ swath beneath the aircraft onto a roll of 9.5-inch film. The second K-38 was placed in a rocking mount so that it alternately photographed the left oblique and right oblique out to $ 3 6. 5^{\circ} $ onto separate rolls of 9.5-inch film. The film supplies unwound in opposite directions in order to minimize their effect on the balance of the aircraft. Both cameras used standard Air Force 24-inch focal-length lenses adjusted for maximum acuity by Baker. The development of the special rocking mount by Perkin-Elmer's Dr. Roderic M. Scott was a major factor in reducing the size and weight of the A-1 system, because the mount provided broad transverse coverage with a single lens, ending the need for two separate cameras. $ ^{16} $
