Re: Eclair Cameras: buying converted super16
Practical tests that I've run don't show an obvious problem when the mirror
is not re-centered --- this may be due, in part, to the fact that the very edge
of the film isn't projected anyway. Or the degree of underexposure may be too
miniscule to show up to the naked eye. But recentering the mirror is
certainly good for cameras with shutter parking.
The shutter is a different matter. While there has been debate on this site
as to whether or not the degree of underexposure of one side of the frame is
enough to be noticed by the eye, (and there are apparently S-16 ACLs out there
using the 175 degree shutter from what I've heard ... especially in
Europe/Australia), there is no doubt that the "eclair factory specs" on the timing of
Shutter and Mirror technically cannot be achieved in Super-16 without closing
down the shutter angle. So all you can do is try it UNDER THE LIGHTING CONDITIONS
YOU'LL BE USING, and view the footage THE WAY IT WILL BE SEEN, and find out
if you notice anything.
Also, a R-16 shutter without ANY modification will prevent the track edge of
the film from being exposed at all! Presumeably if the camera is a "Super-16
conversion" and shows picture in the track area, then at the very least a
minimal amount of filing of the hub was done.
If you are planning to put a lot of time, effort (and $$$) into a project,
converting the shutter is probably worth the piece of mind. If it is a demo
short being made on a shoestring, then that may be a different matter.
(note: a R-16 shutter gery-rigged to close the shutter angle will not balance
100%; a lot of cameras have been converted this way and appear to work fine.
But an out-of-balance shutter could cause vibration that, at the least, might
put undue wear on the shutter spindle. If you have an old ACL 1, you're
probably fine to gery-rig the old R-16 shutter, as the camera's lifespan is going to
be more limited than a newer ACL II. If you have a $5,000 ACL II package in
great condition, it might be best to use an HD-144 shutter to ensue maximum
life --- no sales pitch, just a suggestion).
Mark.
