Canon EF-S 18-200mm f/3.5-5.6 IS repair the wobbling front lens tube

- This video is about repairing the wobbling front lens tube of the Canon EF-S 18-200mm f/3.5-5.6 IS lens. I had a Canon 18-200mm IS lens which had a very loose front lens tube. The front lens was wobbling too much at 200mm. So I had to disassemble the lens, tighten the screws inside, then assemble the lens. In this video I show you how I did that.

Thank you very much. It makes my standard lens worth using it again.
I'm glad that my video has helped you! And than you for the donation!
best repair complete detail...
Thanks 👍
My lens wasn't wobbling - the zoom had jammed. Turned out 1 of 3 brass guide lugs (see them around 10:28) on the Zoom had come out because the screw holding it in had sheared. Using the lens with just 2 guide lugs now! Helpful video - Thanks.
You're welcome, I'm glad that my video has helped you.
@@CamerasLensesEtc Actually, the Auto Focus is now quite slow and doesn't always get it right. Is there some reset or calibration method?
@@WINGNUT307 Most likely the problem is caused by the missing brass guide lugs. Do you have focusing problems towards the end of the zoom range (200mm), but not in the beginning (18mm)? The problem could be that the lens tubes bends downwards when you zoom to 200mm, and that causing the focusing lens element lever to stuck between the zoom tubes, and that makes focusing slow and inaccurate. You might try to switch to manual focus, and check how much force you have to use to turn the focusing ring at 18mm vs 200mm. To solve this problem, you have to put back the third guide lug.
@@CamerasLensesEtc You are probably right. Focusing is fine up to around 50mm. Beyond that i get problems. I don't notice anything unusual when manual focusing. I can't replace the lug as the old sheared screw is still in place and I don't see how I can get it out! And how would I get a new screw? I'll just have to live with it.
Many thanks - fixed my non-zooming 18-200 by taking it apart using this video, couple of bits of black plastic fell out, back together and all is good - sent you a small donation to say thanks.
I'm glad my video has helped! Thank you for the donation, I appreciate it!
Thank You . I like it . Good job
Thank you, I'm glad that my video has helped you.
Very good job thanks
You're very welcome!
Thank you very much
You are welcome
Thank you sir...
You're welcome!
Vraiment très clair et pratique.
Merci
Thank you!
It took me awhile to find the slot for the silver pin (~12:20). If you can't find it, try turning the lens upside-down so that the sliding grey piece can fall into view.
Same here - also, at around 8:55 when you disconnect the middle lens cover, it is useful to first mark one of the 3 screw locations so that you can put the cover back in the right orientation.
Great God save! Very helpful for lens repair! Hello from Russia!
Thank you for watching and your feedback!
Wow muito bom obrigado pelo vídeo
You're welcome, I'm glad that you found it useful.
This helped me fix an issue with my lens where it would not zoom completely to the ends of the range and had a slight grinding resistance. It turns out that one of the brass pins inside had come loose and was binding the mechanism. Using this video, I was able to replace the pin, reassemble the lens, and had it working again. It's a nice lens when it works properly but seems to be a bit fragile.
This problem happens many times with this lens, so I thought I make a video of it... I'm glad it helped!
Nagyon köszönöm a munkád! Remek videó lett. Ennek köszönhetően sikerült saját magamnak elvégezni a javítást és ezzel súlyos összegeket szervízköltségre kiadni. Most öröm a köbön van! :P :D
Örülök hogy sikerült az operáció! :-) Köszönöm a visszajelzést!
Please say how to align the interior dust ring vid doesnt show and no audio instruction.
Can you give me a timestamp?
Is the lens supposed to fall out of it's original position when pointing the camera down or did I get a defective lens?
Zoom creep is a quite common among this lens, and I don't consider that defect.
Damnit! Stumped at 05:42, Screw jammed tight. Any tips?
Do you mean that the head of the screw has been damaged?
@@CamerasLensesEtc Not yet but it feels like it will if I put more effort into unscrewing it. It's in super tight
Hard to tell... I would say use a screwdriver which fits perfectly... there are PH000 screwdrivers which have thicker head, and not fitting perfectly in the head of the screw, and it shave off the head.
But in this case it would be hard to tell if it fits, because you can't see the screw.
@@CamerasLensesEtc It might be the shape of the end of PH000 drive I have. I have two. The one with a bigger handle is more pointed and would definitely strip the screw. I have a shorter 'spectacles' ph000 'keychain' screwdriver with a blunter end which seems to fit better but the 'handle' is too small to get any purchase. I was thinking of getting an iFixit kit but seeing the ends of the two screwdrivers I have are so different, I'm worried the PH000 will be too pointed too.
I'm definitely getting the head of the screwdriver in the right place.
@CamerasLensesEtc help my friend. The head of the screw is damaged. What can I do with it?
You lost one last screw that on the lens contact stopper
Can you give me a timestamp?
