Hi folks -
First time poster here. I have recently become completely obsessed with Super 8 filmmaking. I'm a film scholar (theory-head, that is) who wants to be able to play with film production on the cheap, and Super 8 seems to be the way to go. I recently purchased a Quarz 1x8C-2 camera from the Ukraine as well as a super-cheap Chinon XL-555, and I have a couple questions. I have some photography experience, so I can take reasonably simple jargon.
Concerning the Quarz:
1: The built-in lightmeter on the camera appears to be broken; I've heard this is a common problem. With fresh batteries installed, the meter just stays near the 1.x mark and does not move, though it floats from side to side if the camera is tilted :) I installed Wein-cell batteries (air-ed out), and have tried resetting the meter by turning the dial to manual and back (as suggested on another site). Is there any way to fix the meter, and/or would it be worth it? Or, could something else be the problem?
2: I don't fully understand how the +/- correction on the camera is related to film speed and aperture. Could someone explain this to me? Is the +/- correction only used in auto mode?
Concerning the Chinon:
1: The focus-ring is broken; it works, but if it is pulled backward (toward me), it seems to go off-track, and just spins freely and does not seem to put the camera out of focus. When applying forward-pressure, it works fine. Any solution?
2: There is a small, recessed button on the top of the camera body, near the front (lens-side). I have no idea what it does. Is it an aperture lock? An internal filter switch?
3: What does the backlight control button do?
About Super 8 in general (super-newbie question):
What is the best practice for handling film cartridges? Can a cart be switched between cameras midway through (e.g. in order to use one cartridge to test two cameras)? What is the best way to store cartridges if I have to wait a few days to drop them off at the developer?
