Cleaning the insides on a lens

I thought of that, but I suspected the problems of exposure might
complicate the situation.

 

Not if someone put an expensive ($7000) lens away in a closet for 8
years when it was freezing cold from being outside. What do you
supposed the interior of the lens was like? Had to be disassembled,
cleaned and reassembled.

Not only is it physically difficult, requiring specialized tools, but
unless you re-assemble it in a very dry environment, internal humidity
will cause fogging if you take it out in the cold.

 

Where does he say he reassembled it?

He said he disasembled it, and then basically destroyed it by
chipping some elements and that he was unable to "drop" an
element into place.

That was an expensive lesson, and it's nice of him to pass on the
experience... ;-)

 

Or try some _very_ gentle "percussive maintenance" on it to
see if it can be induced to move to a less intrusive position. Have
you actually been able to spot a flaw in a finished picture which can
be attributed to the bug?

 

Of course I do. It's the reason my godmother started calling
me Housewrecker when I was just five years old. In later years, she
kept a supply of clocks for me to take apart. I think she got them
from second-hand (no pun intended) stores. I don't really know, as I
never checked to see if they were working before taking them apart.

Eventually the observational skills thus gained did lead to my
being able to disassemble and successfully reassemble lots of stuff.

 

Disassembling and reassembling camera lenses (and having them work
right afterward) requires extensive training and equipment not
available to the average individual.

 

Words to live by, the same goes for shutters....take it from the
voice of experience. I once got the bug to fix a Copal shutter on
a Schneider lens, truly a gruesome realization that yes the little
buggers are quite complex -as it many small parts that don't go
back together as neatly as they become disassembled. Never again.

 

No, I saw it done with a Kowa spotting scope. It's fluorite element.
I've never owned one myself.

This was an older, non-electrical lens. I doubt I'd try it with
a new one.
-Rich

 

Same here. Went to adjust the timing of my OM-1 shutter..
I kept the camera as a reminder not to attempt such things in the
future:

I can see whats wrong - the little spring in the left lower part is
upsidedown!

Give the bits to any 8 year old & he/she will be taking Pulitzer
quality stuff on it before nightfall....

 

That would make a neat display if you got one of thos glass-top coffee
tables with storage space underneath. You could lay out the parts in
roughly the relative positions they occupied in the camera, sort of like
an exploded view assembly diagram.

And when you don't want to be reminded of the experience, cover the
coffee table with a cloth.

Unfortunately, there's no enough parts to spread out much:

This also includes the parts of a junk lens I bought and disassembled
just to help fill the jar

 

Oh my. I'm pretty good at taking apart small electronic devices
and getting them back together again in working order, but I'm glad I
didn't try working on that camera.
