I will be using a Bolex P1 regular 8mm camera and my Sekonic meter as backup. I plan to operate the camera at 18 fps with the shutter all the way open. The exposure time is 1/43 sec, or 150° shutter angle. When using the external meter should I also factor in light loss occurring in the viewfinder process? Does anyone know how much that light loss is? I have no filters for the lens, and I will be using ASA 100 Plus X.
