Hi, I wonder if you could help with some advice. I've got hold of a Canon Zoom 518, and am planning to use it at an event, to film in a low light situation. I have no experience with Super 8, or indeed with the moving image, so it's really an experiment, but I don't want to waste an opportunity, money and footage if it's not going to work out at all.
I've been reading the manual etc. and it seems that the lens has a range up to f1.8. I've ordered some ISO 500 Tungsten film (the subject is going to be lit by a bonfire, so tungsten balance is a good starting point). The camera can only detect up to ISO 160 film, so presumably won't detect the ISO 500.
What I'm thinking is that I should leave the batteries out of the camera meter, and let the camera expose without any metering at all. Is there a way of knowing roughly what the shutter speed of the camera is? I'm guessing that, since it takes 18fps, that the shutter speed is likely to be a fixed one of somewhere between 1/20th and 1/30th sec., but the manual doesn't say - is that a reasonable guess, or have I missed something?
Also, if there is no meter battery in, does this mean the camera should default to maximum aperture i.e.. f1.8? I've tried holding the camera up to the light and running it 'dry' without meter battery or film, looking through the lens with the shutter going and judging the amount of light coming through the shutter it looks like the lens is reasonably well open, and the meter indicator needle is resting at the f1.8 end, but am I right that it's default position for the aperture will be wide open?
I took some test pictures with a stills camera in a similar-ish low light fire-lit situation, and the correct exposure seemed to be within a stop or so of f1.8 @ 1/20th sec @ ISO 500. So my logic is that if I leave out the exposure meter battery then the camera will just expose wide open and shouldn't be a million miles off. My concern is that if I put in a battery for the exposure meter, when pointed at the flames the meter might stop the lens down unnecessarily or cause exposure to go up and down like a yo-yo (there's no manual exposure mode).
I'd appreciate any thoughts - is this going to waste a film (and worse, an opportunity when I could be filming in a different way e.g.. stills? I possible, I'm really keen to get some Super 8 of this particular moment, rather than stills.
Thanks in advance.
