A camera includes a finder optical system having an objective optical system and an eyepiece optical system, independent of a photographic optical system, and a range measuring optical system. A path splitting member Is disposed in the optical path of the objective optical system to make an optical axis of incident light introduced from the objective optical system into the eyepiece optical system coincide with an optical axis of the range measuring optical system, and satisfies conditions: 650 nm</= lambda (R0)</=850 nm R0=[R(550 nm)+R(900 nm)]/2 where lambda (R0) is the wavelength at which the reflectance of the path splitting member regarding an axial ray changes to R0, and R(550 nm) and R(900 nm) are the reflectances of the path splitting member where the wavelengths of axial rays are 550 nm and 900 nm, respectively.
