摘要: An exposure meter for incident- and reflected-light photometry includes an incident-light receiving section, a finder for reflected-light photometry, an arithmetical element for calculating various exposure values on the basis of photometric results obtained by incident- and reflected-light receiving elements, a finder optical system for displaying information on the exposure values obtained by the arithmetical element in the finder, and a display window provided on an exposure meter body. The incident-light receiving section is constructed so that it is can be mounted to or dismounted from the exposure meter body and allows incident-light photometry and lighting setting photometry. The exposure meter further includes a transmitting unit, mountable in or dismountable from the exposure meter body, in which flashlight is emitted and the amount of flashlight can be adjusted in accordance with the information on the exposure values displayed on the display window.
