Overwhelming majority of high-speed cameras with optical-mechanical commutation (i.e., rotating mirror framing cameras) has a cylindrical film track' and it results, to a considerable degree, in their enlarged overall dimensions and weight. A rare exception is the high-speed camera discribed in report2 when they managed to design a flat film track by adding a flat mirror to each commutating lens (i.e., framing lens) but the construction became more complex. Thus 48 flat mirrors should be inserted into the optical path at 48 frames being recorded. Nevertheless camerae is rather compact and provided with cassettes of "dry" developing that considerably raises photoresearch work rate. The aim of the paper is to introduce two other systems of mirror scanning, which also allow to get the flat film.
