Eclair Cameras: HD-144 Viewfinder correction for S-16
The "HD-144" specification includes shifting the viewfinder upwards by 1.1mm
to recenter the finder on the S-16 frame. The existing ground glass will cover
the entire S-16 frame, but not the light meter LEDS --- if you have the light
meter, it is probably best to do away with it (unless August has perfected a
process to retain the light meter, which involves modification to optics. At
one point he was prototyping it. This involves installing a reduction lens in
the finder, and replacing the 9 x 15mm convex lens glued to the ground glass
with a longer one.).
The following are the instructions from the HD-144 manual for achieveing the
basic finder modification:
Modification of Viewfinder Mounting
The viewfinder should be shifted upwards by approx 1.1mm in order to
center the Super-16 image. This doesn't require any new parts.
One way in which to achieve this is to slightly elongate the 2 mounting
holes in the finder's mount --- downwards --- so that the finder will move
upwards on the camera body. Then cement some small washers in the new position
with black epoxy.
Depending on the manufacture of the viewfinder, it may also be necessary
to slightly enlarge the opening in the ACL body to accommodate the new
position of the finder. This will be required with Angenieux finders, but not with
the Kinoptic.
