>>>I spent a lot of time looking for a good DP-3 for a F2
so I could take advantage of some great older lenses with the best
non-AI meter/prism I could get my hands on.
>> I finally found one and it was in almost perfect condition but
I
eventually discovered one minor flaw. When removing a lens, the
coupling arm returned to the center but didn't go up quite far enough
to
be ready to accept the next lens. This was easily handled by simply
pushing it up into the opening in the finder about 1/8th of an inch
until hearing a "click". Then it would properly index with the next
lens. It seemed that the linkage was just a little sticky. Rather
than
try and do anything to it myself I checked around at several places
and
f>>ound that nobody will work on those "old things" anymore.
Are you sure you have a 'sticky linkage' problem? From this
description, this
sounds suspiciously like the old Nikon drill: Back in the pre-AI
days, the
metering linkage was external on Nikons. When removing a lens, the
coupling lever
sprung back to a central 'neutral' f/5.6 position. When mounting a
new lens, you'd first
mount it in the bayonet, then do a quick twist&back of the lens
aperture ring, so
that the meter coupling pin would be engaged, and maximum aperture
registered.
Kind of a badge-of-pride ritual, like kick-starting an old
motorcycle, and you
could spot a Nikon user by the way he mounted his lens. Once AI came
out in '77,
some users continued the drill needlessly for awhile (er, me), old
habits being hard to break!
