1/3 di stop di luce sul sensore, neanche tanto. Voglio dire, non è grazie a quel terzo di stop di luce in più che faresti buone foto

In the spectral characteristics of the light-beam splitting mirror 3 according to an embodiment of the present invention, for example, the transmittance at a wavelength of 400 to 650 nm within a visible light region is
65% or more and 75% or less and the reflectivity to the autofocus auxiliary light (wavelength: about 700 nm) guided to the autofocus detecting device 6 is 60% or more. Such spectral characteristics can provide a sufficient quantity of light guided to the image sensor 4 and a sufficient quantity of autofocus auxiliary light guided to the autofocus detecting device 6. The present invention can provide a light-weight small-size digital camera.
