I have recently purchased a Bronica SQ-A with standard waist-level viewer, and hence no internal light meter. I assumed that as I do not have a light meter that I could use my 35ml camera (Pentax MZ-50) instead until I can save up enough to buy one. Thus I set the Sigma zoom lense to 50, standard on the 35ml SLR, to approximate the 80ml lense on my Bronica (standard of 6x6 MF). Determined the exposure I wanted on the 35ml and transfered this to the MF. However the negatives, when I developed the file (HP4 in HC110[B]) were excessively over-exposed.
Is anyone able to explain to me why this occured. More importantly, can anyone explain how I can use my 35ml camera, with internal light meter, as an interim light meter for my Bronica until I can afford to buy a proper meter?
