ABSTRACT:
In one arrangement, the exposure multiplication indicating means includes an exposure multiplication selector dial having a small window cut therein and numerals marked thereon representing exposure multiplication, a film sensitivity dial, and an indicium. Numerals marked on said film sensitivity dial for representing the film sensitivity are observed, one by one, through said small window cut in the exposure multiplication selector dial, and the exposure multiplication is indicated by the numeral which is marked on the exposure multiplication selector dial in alignment with said indicium. In another arrangement, a main switch energizes the automatic exposure setting circuit and also energizes an element indicating the exposure multiplication setting. A source voltage confirming circuit enables the exposure multiplication indicating means to operate only when the source voltage is of a predetermined value.
