Question about Canon EF-S 17-85MM F/4-5.6 IS USM Lens

3 Answers

17-85MM IS - mechanically stuck at 17mm - will not zoom -

Hello - My EFS17-85 IS USM has zoom ring stuck at 17mm setting.

I can move the zoom ring a little bit only - say about 2mm of travel.
On camera, lens focuses in manual and auto, and IS seems to work also.

Nothing rattles. No loose parts, it seems.

It definitely feels like some sort of mechanical problem, and I am comfortable taking gadgets apart, but I need guidance. The fee from Canon is a little hard to choke down.

I really appreciate any assistance.

Best Regards,

    I have the same issue--stuck at 17mm. I don't mind taking it apart, but I don't want to turn a $100 fix bill into a new lens bill. Any help would be appreciated!

    Hi I have the same problem - It started during my vacation in Peru - where I really needed the camera. Canon in Lima ficed it, but now, I am home, it is stuck again.

    Is this a general problem with this lens??

    Basically i expext a robust quality from Canon - that doesent let me down, when I need it.

    I used to have a Nikon F - a very robust thing. I whish for something like that

    Same problem you all have!!! New 17 - 85mm EFS and mechanically stuck at 17. I thought the kids may have done something to it, but it looks like it's a design glitch. Please help. I guess the warantee should cover this, but holidays are coming up and I don't want to send the camera in.

Hi all,

I've had the same problem. So I decided to give it a try because I didn't find any solutions on the net. Unfortunately you have to pay pretty much for a Canon lens while the internal quality is pretty cheap, the whole mechanism is of plastic and this is also the problem. And after a while some screws will vibrate loose from the plastic components and canon could have done this better.

Probably within your lens is now one of the three zoom mechanism screws complete removed and you will notice that there is some abnormal movement in the zoom part. Unfortunately these screws are deeply mounted inside the lens and you need a lots of skill and patience to get it fixed.


First you need to completely disassemble the lens, and please make a picture of your lens after every step you make because I had to disassemble my lens 4 times! Because some of the elements was not right in place.

I will try to place a more complete description later today including some pictures.

Regards Gert

    Hi all,



    I wanted to edit my unfinished answer above but unfortunately I’m not able to edit my own solution. I asked the support of FixYa to remove it. But I’m also not able to post a complete manual on the crappy website because I’m exceeding the message limit. But I really would like to inform you that there is a possibility to fix it your self.



    So I’ve written a manual and posted it on a free file share website.



    This is the issue with the stuck of the zoom ring: The Canon lens is an expensive lens but build with cheap plastic materials. And due to the frequently use of the zoom mechanism the screws will become loose from the plastiic and at a certain moment the screw will completely be removed out of its position and will stuck somewhere in the lens. This causes that your zoom will lock.



    To solve this you will have to completely disassemble the lens which is pretty hard because the real zoom mechanism is deeply inside the lens.



    With the link below you can download my solution. Hopefully you’re also able to fix the lens.



    Best Regards

    Gert Jan,

    Picture where the screw is missing





    Parts to be removed






  • Gertus Dec 04, 2008


    I would advise you to make good close-up pictures of every step you make. Because I had to

    disassemble my lens 3 times! Because I didn’t know the right position for some elements mostly in

    the focus ring. But I think you could leave the three metal rings from the focus area in place, this

    will save you a lot of precious work and time.

    Also use a screwdriver which exactly fits, otherwise you’ll damage the screwheads.

    For the steps below see the numbered image at the bottom of this document



    • Remove the aluminium ring at the back, (1)


    • Remove the two little screws in the connector


    • Tilt the ring a little and push with your thumb the black plastic inner part from inside to outside (2)


    • Remove the plastic housing and while removing use a little screwdriver to remove the cable rom the print (3)


    • Remove the cables from the print, one screw, and remove the print (4)


    • Remove the plastic part (5)


    • Remove the focus ring (6) but you probably can leave the metal rings in place (6a)


    • Remove the ring sticker at the front (7)


    • Remove the three screws and the front lens (8)


    • Use a little screwdriver to remove the rubber zoom band (9)


    • Remove the three screws inside the zoom unit (10)


    • Remove the three screws/rings at the side of the second zoom part (11)


    • Now you should be able to take out the inner lens-unit (12)

    Hopefully you’ll have the same problem and is there only a screw missing in the zoom-part. Return

    the screw at the original position and use loctite or something like nail polish to prevent the

    problem for the future. Now put everything back in the reverse order.

    Hey Gertus. great manual on fixing the zoom problem. I have a 17-55 f2.8 IS USM Canon Lens that I dropped and the zoom ring would zoom out but not in. I followed your manual to take the lens apart and even tho they are not the same it helped a lot. The only thing I didnt read was your do's and donts and I have removed the focus ring. Now I put it back together and the focus doesn't work. Did you have a similar problem and if so what did you do to fix it.??? Any help would be great. Cheers Bud.

  • longy77 Aug 20, 2011

    All sorted. I read a little further and found out I didnt have the clip in place when I reinstalled. If anyone knows of a site to pick up parts for canon lens please let me know. cheers

I have just followed Gertus' instructions, it worked great! Some additional points:
- "print" = printed circuit board.
- There is a third screw attached to part (1) : it stops the lens from swinging around too far when attached to your camera body. I lost it - oops!
- Part (2) has four clips inside that hold it in place, I broke one off but things still hold.
- I concur with the comments on parts (6a) : they do not need to be removed.
- To remove part (12) there are three screws on the back, there are about 10 different ways you can reattach them, so TAKE A PHOTO!
- When reassembling make sure you feed the two ribbon cables from the zoom mechanism (12) through the main lens body - I forgot the first time and had to pull it apart and try again.
- When putting the zoom mechanism back in place, be very careful of the delicite wipers that slide along the small PCB - these are sensors for the focal length (captured in EXIF headers)
- When placing the zoom mechanism (12) back inside the main lens body a black plastic tab needs to run between two silver metal guides. If you do not, the lens will go back together but the focus will be WAY off.

My Canon 17-85 IS F/4-5.6 IS USM zoom ring locked at 17mm. Any ideas how to fix it?


The most likely cause for this is faulty zoom guides within the lens. This will require complete disassembly to repair and can be done fairly inexpensively. However, it's not really a user serviceable problem and should be done by a qualified service technician.


My name is Rick and I'm a professional repair technician with over 20 years in the business and have repaired many of these. I'm semi retired and work from home with little overhead so I can keep repair costs low. If you decide to have the camera repaired, please click HERE for a directory listing that suits your needs.


If this response has been of any help to you, please be sure and give a positive vote for me on FixYa.com.

Zoom ring stuck at 17mm.


This is most likely caused by one of the assemblies comming loose inside the lens. This will require disassembly to repair and reseal. This can be repaired fairly inexpensively. However, it's not a user serviceable problem and will need to be repaired by a qualified service technician.

Canon 17-85 IS zoom ring locked at 17mm.


Sometimes, if that lens has heavy use or if it has been traveled with a lot, several of the internal zoom screws may come loose deep inside the lens and cause the zoom to freeze. It requires a complete disassembly of the lens to reach the screws and re-seal them so it does not happen again.

Stuck zoom too!


I had the same problem, but it was a case of getting a loose screw tightened up inside the lens.
I took it to an authorised dealer and it cost me the equivalent of about US$25 to get repaired, with the obvious advantage of not messing with the warrenty.
I also hadn't bumped my lens, and I only bought it in July, 2009.. so effectively, new. I did notice the zoom getting looser with time, and would fall out of the chosen zoom length when pointing down (and indeed, up).

Canon EFS17-85 mm Image Stabilizer Lens stuck in Macro mode.


The USM focus works by applying pressure to a set of rollers. That pressure is achieved with a large diameter spring washer. It is held in place by another large diameter flat washer that on assembly is rotated 60 degrees to lock it in place. If the lock washer has moved due to mechanical movement (ie rapid manual movement of the focus ring) it could unlock and then all pressure to the USM motor parts and rollers is lost giving the loose feel you mentioned.

You will need to dissassemble the rear of the lens to see the USM motor parts, rollers and locking ring to reattach it. Follow the links at my pbase gallery to see the dissasembly. When I took my lens apart the focus and USM motor went all loose and I wondered how could it work ever!!!. The locking ring was off which sounds just like your fault. http://www.pbase.com/barry_2718/efs1785mm I also have a flex cable cracked which is a much harder fix. Take careful note of the parts (mark then with a felt marking carefully) to achieve a reassembly exactly as removed.
