Hello,

I've got a Canon Auto Zoom 518 Super 8 camera and am really excited to clean and use it. I haven't been able to look up what shutter speed to meter for. It shoots at 18fps and "High Speed" which I've read is about 36 or 40 fps but no manual or guide mentions the shutter speed at either setting for manual exposure calculations.

Does any one know what it is or how to test it to determine the shutter speed?

Thanks,
Joe

Hello, Joe

A shutter angle of the Auto Zoom 518 is 160 degrees.
"Slow Motion" is about 40fps.

18fps --- 1/40.5
40fps --- 1/90

There is a little loss because it divides light into the finder with the prism.
About 1/3 Stop.
Please correct shutter speed of the exposure meter or ASA.

Good luck!

Oh that's great!

so I guess that I could consider it about 1/54 at 18fps and about 1/120th for slow motion to compensate for the viewfinder prisim.

How did you figure out the 160 degree shutter angle?

Thanks!

Hi, Joe

Most 8mm cameras are 150~160 degree.
And the "XL" camera is 210~230 degree.

There is information in the site of Canon.
www.canon.com/camera-museum/camera/index.html

There is a camera not put on the market in Japan either, and it is interesting.
