Exposure Measuring Range and Ev
The exposure measuring range with the RF645 is EV3 to 18 (with ISO 100 film).
For example: If EV 14 is the correct exposure with ISO 100 film, the shutter speed setting will be 1/250
sec. when f8 is set to the aperture ring. If the aperture is adjusted to, in the above case, the shutter
speed setting will become 1/125 sec.
*An EV 14 is the brightness outdoors on a bright sunny day.
