you really can't SEE it... but you can feel it ... a photo cant show much...
......
it is as if i put some chem on it to clean it...which I never did...
or maybe it is just a batch of the rubbery 'grip' stuff...that went bad?...

Feels like a steering wheel that's been in a hot car too much right? Not saying the lens was in a hot car, but that is probably how it feels... kind of sticky. I'd send it to Canon. Maybe the batch of rubber was mixed poorly.

the rubberized coating on my 3 yr old 85L mk II seemes to be breaking down...
feels a bit gummy/sticky ...

...  can it be restored...or better yet would canon consider this a defective material issue and ..can it be re-applied  by them...?  if they can replace/repair  is it expensive ...if they wont cover it...

it has not separated but doesn't feel like it is gonna last.....


the lens is dead-on accurate .... just the finish on the rubber makes it... lower value...I suppose
thanks for advice.....

Are you talking the rubber focus ring?  I don't think that there is any other rubber.

The rubber rings are just a rubber band that will stretch to attach and detach.  Ask Canon for a replacement, or buy one, they are cheap.

That is nice information. Thanks! I learn a lot from you.

Canon's warranty won't cover this as it is a 3 year old lens.

I'd still send it in unless there is a third party that supplies the part... or get the part direct from Canon if possible.

thanks all you informed and ...sharp minds..

I decided to send the lens....to Canon for an estimate..
they have always treated me good.. (NON-CPS)
pro photo portland is sending for me...where I buy stuff...

I will guess $150 to do it right...
which is about 1/2 case of fairly good wine...
(how I measure things)

I assume they will clean up and make like new...
I could be wrong though..

the lens is a sell/dont sell ...constant  item in my head...
because I want the new version of 85-135 range with stabilized  function...
MAYBE if I am lucky..
they will make a new 135 I.S. f2..
and I will keep the old bokeh...master...

the 135 was like the 200 f2 but 'shakey' ..

so I am SURE they know they want a 135 I.S.

also I would get the 200 f2 mkII version.. if out soon..

..

all this talk triggered by rotting rubber....
the comment that it was organic and ...it reacted with organic...made sense.. I never put anything on it.. not armor all or windex....etc.. just water on a cloth... because it was in a limited environment...
///
so ..
my duty to report the cost...and outcome to my friends who helped with so many good ideas..

....

lucky to have these places to chat

well
Canon wants a flat rate $327 to replace the rubber grip..
I suppose they have someone clean it and run it thru production..
I get 6 mos warranty......til the new rubber breaks down I guess..
....

seems a rip...but labor is high..
supposedly it is re-calibrated.... etc..

but it was dead-on accurate 1-2 micro adjust clicks if that..

sigh..
and I read that the rubber part is $27 from canon...

...

I will ponder this.....sort of stuck....
I wonder how difficult it is to do...
clean and then properly glue.. the part on?

has anyone ever done this or seen a video of it done?..

thanks if anyone follows up on this post..

TOM

ok
I refused the repair..
because it SEEMS like the rubber assembly is a shell ...covered in the 'grippy' substance..
and no gluing///cleaning required..

so 3 screws hole the assembly on..

seems like a 'sleeve'....

so I will try it myself....
.......
$27.48 + $7 shipping
and 3 screws...
versus I screw from canon repaeirs...ok...
seems a bit much..
however I do understand the repair business 
once they 'touch it'  they own it for the 6 months warranty...

.........

so
I will report this progress...
////

J.R.  you are my personal hero..
if this works as it seems it may...
you saved the day...

so...
pending success of the repair..by me...

if you ever are in Portland Oregon...
I will drive you thru the wine country ...on a personal tour..
including the samples costs etc...and lunch...
...
thanks for that tip...
about the $27 part...

I await the return of lens and arrival of the new part...

Goo Gone in the spray bottle works wonders on the sticky rubber coating fail. You have to scrub the %$@# out of it, but it does come off. It is exactly like a tacky steering wheel and starts with dirt/grime and oils from your hand combined with heat etc...

Never had it happen on a Canon Lens though.. Mostly Nikon Bodies

Great to see that it worked out!
I took a hiatus from CR for a year and a half. The discussions haven't changed much. Excellent information is still being shared while people bitching about Canon cameras are still bitching and haven't moved on to Sony

thanks again J.R. ....
you helped me a lot with the tip....


and Tet...your comment above....my brother said the oils in my hands were likely the cause...
he is a jet mechanic (retired) and motorcycle racer now...
pretty skilled...fixer
he mentioned the hand oils first thing..
if you touch a bearing with bare hand... you cause troubles...

and I wonder if the moderate heat added to the trouble...like you said..

for Canon...I say good design where you can slide on a replacement..
and of course if they 'repair' the lens in anyway...they sort of have a risk of responsibility
for anything that goes wrong..even if it seems unrelated...
they calibrate, certify and warrantee the lens for 6mos..
so I cant really fault them too much ...for the big price...

the thing about this forum and others is...
we help each other ...all the time...

thanks again to all
