<p>Hello</p>
<p> I have a rangefinder camera that has the "flashmatic" system on it. With the Flashmatic system, you just set the guide # setting on the camera, and focusing it opens or closes the aperture to the proper size for correct exposure. I have a small flash unit with a guise # of 50, with ASA 100 film. So that would give me a guide # of 100 with 400 ASA film. The guide # ring on my rangefinder is in meters, they are, 7, 10, 14, 20, 28, 40, 56. So which setting would I use for a guide # of 100?<br>
