Hello all! My first post here... I have just bought a 1977 Bronica ETR-C Medium format camera. I would like to know how I can light meter? Is there one built into the camera? I dont know how to use it if there is! I have looked at the manual and I cant seem to find aything about it... Will I need to buy a light meter? I usually use digital, or newer 35mm cameras which give you digits for exposure, but I just cant see how I can meter with this old camera! Little help? Many thanks in advance. Elliot.
