71. LIGHT METER RANGE
The table shows your camera's light meter range with films of various speeds. Since the range of ISO/ASA 100
is from EV 0 - EV 19, the range with an F1.6 lens is from EV 1/2 (at F1.6, 2 sec) to EV 18 (at F16, 1/1000
sec.) It applies to the camera's
built-in exposure meter's measurement for aperture-preferred and stopped-down automatic exposure as well as
manual.
