I believe the HPX-170 sensor is rated at about 500iso. Is this correct? I've heard the Brevis MP.1 only loses about a half stop of light. Is this correct as well?
So the hpx brevis combo would be roughly a 320? If I wish to stop down the hpx to f4, what iso should I be setting my meter to?
Sorry if this question has been answered many times before, I searched and could find nothing. If you could direct me to the proper thread I'd greatly appreciate it.
ISO rating - HPX-170 with Brevis MP.1
