Фотокамеры для аэрофотоснимков Rb 20/30, Rb 50/30 и Rb 75/30.
The German Luftwaffe used a very simple way in which to identify their cameras systems, all reconnaissance cameras had either a two or three letter code followed by two numbers, a diagonal slash and then a further two numbers.
The letters stood for the type of role the camera was to be used in and could be from the following, Rb - Reihenbilder, shorten of the original name - Reihenbildmesskammer - series-picture, topographic camera, NRb this indicated that the camera was used for night photography and HK - Hankammer - Hand camera , it was also known as Fliegerkammer - flyer's camera. The first number would be the focal-length of the lens in centimetres and the second set of digits would be the film format size, again in centimetres.
So for example, Rb 50/30 would be a topographic camera with 50cm (19.69 in) focal length lens and a film width 32cm (12.60 in)
