Claims

[Scope of utility model registration request]

In a lens-shutter camera that has a shutter either inside, immediately before, or after the photographic lens, there is one light-receiving element for photometry, and a light-metering optical path for display that guides external light, which is light reflected from the subject, to the light-receiving element for photometry. a second optical system that forms a photometric optical path for photographing that guides light reflected from the film surface during exposure to the photometric light-receiving element; A film surface that guides only external light introduced through the system to the photometric receiving element, and is introduced via the second optical system from immediately before the opening operation of the shutter blade until at least the shutter blade closes. 1. A photometric device for a lens shutter camera, comprising: an optical path switching means for switching a photometric optical path so as to guide only reflected light to the photometric light receiving element.
