Why ISO setting on RZ67 film back

ignacj · Mar 11, 2010

Just wondering, unless using AE prism or purely as a reminder of what film is inside, is there any other reason for ISO wheel on a film back? Maybe for MZ36R flash?

I have 3 backs that look almost identical but are loaded with different film speed. The little "tab" for keeping a film reminder never keeps the paper in, so yes, it is a reminder. I sold my AE prism years ago but do you not set the ISO on it?

Don't have AE prism, so I wouldn't know. With 120 I prefer to do all my metering by hand anyway.

No, the ISO is read from the back.

If you don't need the reminder and don't have and AE prism there is no need to set the film speed on the back. As far as I know there is no TTL Flash metering on the RZ.

I always set the ISO to the speed of the film loaded in the back, just in case I put the AE prism on. The little tab that is supposed to hold the film type is kind of useless for some films - notably Kodak's C-41 films. I never get a box when I order them from B&H, and trying to tear the foil wrapper in such a way that it will fit and stay put in the tab is nigh impossible, especially out in the field. So I rely on the ISO dial first to remind me of the speed - and dial in an appropriate compensation to it when loading the film as well (C-41 vs E-6)... that way I don't have to know what's in the back at all when I use it.

I can't remember.

ae prism. meter in the AEII prism works quite well. I've rented the aeII prism before, and it was a nice feature to have, however now, I take meter readings by hand 95% of the time, so its not needed.

I use blue painters tape with the film type written(TX, TMY, EFKE25, etc.) on it stuck to the back instead of using film box tabs, which always fall out.

Ooh, that's a clever use of that tape Dan... I may have to try that!

Second vote for blue painters tape. After I load the film on the reel for developing I move the blue tape from the camera to the tank lid to remind me what's in there in case I don't develop it right away.

I save and re-use my film box ends, and put them in backwards when there is no film in the camera.
