ABSTRACT:
An imaging apparatus, includes a viewfinder optical system for guiding an observation light beam to a viewfinder window, the observation light beam being output from an imaging optical system and then reflected from a main reflective surface, an imaging element for generating an image signal in response to the reception of the observation light beam, an exposure control unit for performing exposure control of the imaging element in response to the image signal from the imaging element, and a light sensing detector, arranged in the vicinity of the imaging element, for measuring light. The exposure control unit determines an exposure control value in the exposure control in response to a light measurement value provided by the light sensing detector if a predetermined condition is satisfied.
