how old was the lens. I heard the ball bearing might be worn out so you can't tighten it

if you overcrank the tightening ring, you do risk the chance of crushing the mini ball bearings inside. Once they break, you'll run into the situation you are experiencing. your lens will need to be sent in

Friction ring problems are quite common with this lens, at the end of the day all that's in there is bearings and cardboard, I have known bearings come out and jam the whole thing up and damage the barrel.

Cardboard? There was no cardboard in mine when I had my 100-400 serviced a couple years ago.

There's a molded plastic ring with four fingers that grip the barrel of the lens and when you tighten the locking ring, that compresses another ring that runs around the lens at about the middle of the fingers.

There must be a couple different ways things can mess up inside. When mine failed, I never saw any foam nor any scratches on the barrel. My locking ring went from needing about an inch and a half of travel to about a quarter of an inch to lock the zoom. Eventually, the lock would not fully release and the zooming motion became very stiff.

In mine, they had to replace the "cam" mechanism that's driven by the locking ring. The "finger ring" was also replaced (guess it was a complete repair kit) but I was told to hang onto it as there was nothing really wrong with that part and someday, I may need it.

Yep, that's it. It just happens after being used for a long time. It gets a bit tight, then little bits fly, then nada.

I think my repair was $113 including shipping for that problem.

Great lens. I will never sell my copy.

Thank you very much Mr. Horton
I will seek where to send.

He bought the lens from me about 4 weeks ago or so, I know the tightening ring works because I used it :) Just wanted to make sure, did you hold the focusing ring while turning the tightening ring ? Otherwise it'll just spin. As for the black foam you mentioned I didn't see any myself, and I don't think that would have happened in shipping, you are sure it wasn't something from the packaging maybe ? Just trying to figure it out here.

Thanks Beetle, appreciate your response and PM.
I never mentioned buying it either from you or the board.
You joining the conversation reflects on the honesty of the sale.
the black "material" stopped coming out after a few days. at first I thought it
was packing material, but alas.....

thanks for some more in depth information flying photog


for the record I love the lens and have taken some of my favorite candid street portraits with it. Tomorrow (Sunday) it will see it's first race..Brazilian Grand Prix in Glen Cove on Long Island.

Thanks to all who helped figure this out. Even the "read the manual" comment and muusers funny turn it the other way

No problem, it's not because you got a "steal" that I will not care that you are having problems with it lol, I want to make sure you are satisfied.
I am puzzled by this though because I used this lens the couple of weeks before I sold it and didn't notice anything wrong with it. I have another 100-400 so I would have been able to tell if something was different.
I wonder if that locking mechanism just fails all at once or is it gradual, you would think it would be gradual.
I learned a lot from this thread, I didn't even know how the locking mechanism works and I learned that it can fail and has failed for some people in the past, I'll be looking for the symptoms now.
The way I usually use it it have it locked all the way at 100mm when stored in my bag or case, and when I am ready to use it, I unlock it so it moves freely (no resistance) and since it's mostly being used at 400mm (taking pictures of planes on a FF body) I just hold it at 400, not locking it, I just re-lock it when putting it back at 100mm when I walk around (it's on an R-strap) and when I store it. I wonder if there is a way to do it to save that mechanism to fail.
Does it not lock at all or does it have a really slow creep ?

When mine failed about a year ago, it was sort of all at once. Well, it actually took about an hour to happen, I was shooting a soccer game during the fail. I didn't see any material come out, the zoom ring felt a little stiff, then zooming became a little more difficult, then it locked up at about 135mm. Had it fixed, and it's better than ever now.

(he was such a great buyer )


Was a ''good'' deal mr B. a steal.........
I am very satisfied with the lens and our dealings.
And I wouldn't hesitate to deal with you again either.
Thanks beetle


Funny that it goes two ways.....some have had theirs lock up others fall free.
Everyone is in agreement that the liked/loved the lens even more after service.

Yes. I was hoping mine would come back exactly as sharp as it was, and it did.

I would have to agree, it either locks up completely, or free-spins.
My lens performed very well when I bought it, but after the repair, it seemed not quite right. I kept using it anyway, but after a couple of months, it got worse. Canon ended up replacing several lens elements along with the IS system. It's like a completely different lens now.
