I admire your courage and skill. I have a
complete Exakta system inherited from my dad and the
Angenieux telephoto is showing what I believe is
separation, although it might be something
else. I need to sell the camera, all three
lenses, the bellows, etc., as a set but the lens
is now a liability and I don't think I will risk
disassembly. Still looking at options.
[Even worse, with respect to my lens skills, is
that I have a Balomatic 755 projector for which I
disassembled the projection lens for cleaning and
am not sure all the elements are in the correct
locations and orientations. Top this off with
the fact that my undergraduate degree is in
Physics. I understand lens theory but am clearly
not a practical optical engineer.] I've thought of sending it to Dick
Knoppow to ask him to have a look. Actually, I
will be going to San Diego in November and I
think he is within driving range from there.
Well, back on topic, lens cementing. During the
time I had my Rolleimarin I wanted some gentle
(CC-30R and such) filters. Up to 20-30 Ft.
underwater they can do a fairly good job in
correcting color. Beyond that it's flash-only or
accept the natural color for long shots.
I worked for a company that, among other things
made capacitors. Than means they had vacuum
systems. I got some Kodak gel filters and bought
some thin glass rounds from a company once famous
for movie effects filters, Harrison and Harrison,
apparently no longer in business. I was able to
pull a vacuum on some clear epoxy, drop the
assembly together, and had some very nice "glass"
waterproof filters. They never got wet so
waterproof wasn't an issue. They fit perfectly
in the Rolleimarin filter turret. I made
equivalent filters for my light meters but they
were simply gel covered with available laminating
plastic. Using the same filter on the lens and
meter did a perfect exposure setting.
Beyond that I will have to look for someone to
have a look at the Exakta lens. My guess is that
fixing that one lens will cost more than the whole Exakta system is worth.
Does anyone know of a company which can take a look at the Angenieux lens?

*Just saw Richard's note on lens
cementing. Very instructive but I still don't intend to open the Angenieux.
For folks who understand, not a single "Trick or Treat" person tonight.
