Anybody do a home disassembly and cleaning of this lens. I have a
nasty
white hair on the outside of the second element and some dead
curled-up
creepy crawly on the inside of the second rear element. I'm not
impressed
with the dust seals on this lens so far as it is only 2 months old
tomorrow;
but the optics are great.

Das Machine is nicht fur gefingerpoken und mittengrabben. Ist easy
schnappen
der springenwerk, blowenfusen und poppencorken mit spitzensparken. Ist
nicht
fur gewerken by das dummkopfen. Das rubbernecken sightseeren musten
keepen
das cotten-pickenen hands in das pockets - relaxen und watchen das
blinkenlights.


Wow, that was some of the worst Faux Deutsch Ich habe gesehen. I am
thoroughly impressed with your lack of abilities and the utter uselessness
of your reply.

Thanks for trying, Please don't try again.

I thought it was quite funny, Jim.
-All in good fun...

I apparently made a mistake in asking what I assumed was a simple 35mm
equipment question to this group. You all have my deepest and sincerest
apologies for troubling you all with an on topic post. My mistake, I'll
try
not to do it again.

Jim Kramer

You asked a simple question...yes.
But that's not the problem.
I think it's a safe bet that very few people have had need to disasemble
this particular lens, and those few who have--likely haven't seen your post.
You've asked a very specific question that requires a SINGLE and UNUSUAL
specific experience that most with this same lens haven't had need to gain.

Nobody's ignoring your question...we/they/I just haven't taken apart our
28-135 IS.
If I had taken mine apart, I'd be gladly answering you here, as I'm sure
may other would.

Well, go right ahead...open the sucker up! Use an old dishtowel to wipe
the elements clean of whatever crap might be floating around in there. I
mean it's only an IS lens, I'm sure it will be fine.

Jim, take a look at a copy of Canon's "Lens Works" I have an older copy
(version 2) and it has a sectional drawing of a 28-105mm USM lens (which
is a cheaper and simpler lens than yours). I think the drawing will
scare the crap out of you. If not, good luck and report back how you did
it. I have sympathy as I badly dusted my 28-105 in the desert and the
Canon (Australia) quote for a CLA was about half the price of a new lens.
They advised in my case that it would be better to live with the problem
or buy a new lens and sell the old one "as is". I did nothing and over
time the graunchy zoom mechanism has become smooth again.

Just for the sake of reference:

....but it's just for available parts, not assembly instructions.

Questions on this ng regarding the dismantling of lenses typically
draw a "don't do it" reply. We are, in the main, photographers, not camera and

lens repair people.

Alan-

No doubt you are correct regarding the people who hang out here. But it IS an
"equipment" newsgroup!

I've been known to disassemble a lens. (All right, it was from an Argus C-3.)
Quite by chance, I found an internal element spacer that was non-symmetrical
and had been reversed. By re-reversing it, the original problem went away.
Then I was faced with the problem of re-aligning both the lens and the
rangefinder, using ground-glass in the film plane.

Assuming you had the necessary tools, and that the Canon lens could be
carefully disassembled, cleaned and reassembled, you would then be faced with
realignment, or at least verifying it. Equipment required for such a
sophisticated lens would be more expensive than the lens.
