I own a GAF 738 that seems to shoot perfectly exposed footage, but the built in meter reads 2 stops faster than a profesional hand held meter (that I have checked with a tech). Unfortunately, I did not test it before I shot that first role of film, so maybe the meters agreed at that point. Also, the trigger seems a little finiky. Other than that, I love the camera. It takes very sharp footage.

Does anyone have a manual for this critter?

Welcome to the forum! [Smile]

Can't say I've seen a manual for this one, but the difference in exposure measurements could well be because of the camera taking such things as its own lens, the shutter (exposure time per frame), super-8 cartridge notching, daylight filter and light diverted for the viewfinder into account. Since your footage comes out fine I wouldn't worry about it.

BTW, generally http://www.filmshooting.com is a more suitable place to ask camera-related questions. [Smile]

Thanks for the response, that makes sense. I did take into account for the notching and the built in 85b filter. So I sould take that as f stops versus T stops, I'm surprised at a 2 stop difference between f stop and T stop. Also, I thought the light was taken for the viewfinder when the shutter blade was over the gate (ie closed).

Hi,

there's no shutter-angle listed in the Super8wiki. Hence I guess that it's 160°. But it could be only 120° or 140° as well. Hence unless you've found that data in a manual, there's still a slight chance that your calculations are based on an incorrect shutter-speed.

BTW: The camera has got an integrated "Wratten 85" as nearly all other Super8-cameras. There's no camera with an integrated "Wratten 85b".

As for registering on filmshooting.com: You can still register. Nevertheless your account has to be approved manually by the admin (who is currently on vacation if I got it right). This causes a "slight" delay in registering, but was a necessary step since the filmshooting.com-forum was flodded with viagra-spam from new users.
