ive used an eumig sound 65 xl camera, all these super8 camera's are made for hobbyists.
handeling this camera can be compared with playing the guitar.
there is a exposure offset knob, you can rise it with one stop and 1 stop the the other side.
you zoom on a grey scale and then you adjust it, till it meters the same as on your external light meter.
while shooting there is a exposure stop knob, so you put your hand in front of the lens or something else, till
the right stop in your viewfinder appears, you keep pushing it while your shooting.
The lens was pretty sharp, after the telecining we have putted a unsharp mask as an additional layer,
to soften the picture.
i hope this make sens
