Bolex 16mm Film Camera
The Bolex H-16 viewfinder enables accurate focusing and framing and allows you to estimate the depth of field.
The reflex prism deflects 20 - 25% of the light passing through the lens into the viewfinder system: only 75 – 80% of the light reaches the film plane. The quality of the light reaching the film is reduced by about 1/2 to 1/3 of an f-stop.
To compensate for the light reduction, Bolex has determined that the effective shutter speed for the H-16 camera is 1/80 of a second rather than the standard 1/65 of a second. Another compensation for the light loss is the RX lens. The RX lens is calibrated to pass 1/2 to 1/3 more light than the aperture markings on the barrel indicate.
