Re: 17-85MM IS - mechanically stuck at 17mm - will not...
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

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.

Hi Thanks for using FixYa. To start with try to blow
compressed air around the lens cover so that if there is any dirt it cleans if
off. You can also stick a thin strip of paper between the lens shutter and the
outer support ring & move it in a way that it clears the debris that’s
stuck in there. If still the issue is not resolved then you’ll have to replace
the lens assembly & lens mechanism to fix this issue. It is recommended to
be done by a professional. Please do accept the solution if the issue is resolved
or post a comment for further assistance. Thanks Rylee
If you try turning on the camera with the lens cap on, you may get zoom error. Ensure that you are removing the lens cap before turning on the camera.
If the autofocus ring is held while taking the picture, or operating the lens this will also cause the Zoom error message coming up.
If that is not the problem, then the lens has troubles extending. This may happen because of dust stuck in lens mechanism, or because of a mechanical fault concerning the lens. Any cause preventing lens from full extention or retraction will trigger zoom error.
Hello Pittsburgh! I lived there for 3 years! Dreadful city. :-)
Now, your lens must have a problem with the guide rails/pins. If you dropped it or bumped it, you might have broken/damaged those guide rails. Another reason might be sand/grit in the zoom mechanism.
You may try stripping the lens slowly and see if you can identify the problem. Most lenses are easy to disassemble, you start from the rear mount area, take off screws, and parts one by one, and be organized (i.e., take photos for every step and don't mix the screws).
Are you sure it's the zoom ring that's stuck, and not the focus ring? The focus ring doesn't move when the camera is in autofocus.
If it's indeed the zoom ring that's stuck, you can spend more money than the lens is worth in repairs, or buy a replacement (circa 35 dollars on ebay) for dreadfully cheap. Good luck.
Just fixed the same problem on mine. This is what I did: Unscrew 6 small screws around the lens casing and remove the casing (two layers ((rings)). Jiggle the inner most lens casing while you turn power on. The lens moving (i.e., auto focus) mechanism becomes unstuck. Voila. The problem in my case was caused by the dust that accumulated inside the casing and caused the auto focus mechanism not to move freely. Good luck.
If you're on a budget, the 50mm f/1.8 II is a great deal, $100ish, f/1.8 is great for low light.
If you have a bit more cash, the 50mm f/1.4 has better build quality (the 1.8 is all plastic) and much better autofocusing (its USM so its fast and quiet, as well as more reliable) and its also slightly sharper.
If you want a zoom, from canon theres the 17-55 f/2.8, which has image stabilizer and USM focusing. Also, the 24-70mm f/2.8L, which has USM, and since its an L lens, fantastic optical quality. However, it will run you over a thousand most likely.
From sigma, theres several zoom options, the 28-70mm F2.8 EX DG, 24-70mm F2.8 EX DG MACRO, and 24-60mm F2.8 EX DG. All under $800 or so.
Check the camera's "shooting mode". By default "digital" zoom is NOT on. Instead, according to the manual, you actually have to set it on as part of the camera's shooting mode setting. It's accessed from the main menu (Ok button), choose right arrow, then up and right to choose the "camera" settings. You should see the setting for "digital" and you may see it's OFF, in which case just turn it ON.
There is also a group portrait mode shooting program that can set the optical zoom to WIDE only. This is accessed by hitting the left arrow when you turn the camera on (the circle with the dots). By default it should be "P" for auto program, but if it's set to the icon with 2 people in it, that appears to set wide angle only.
Alas, I checked this last thing on mine and it just seems the lens is stuck (I hear a short whir and that's it, and it is set on "P"). Any suggestions for a mechanical repair?
There is no easy fix, you?ll have either disassemble and get dirty, or take to an authorized repair person. This zoom error problem is usually caused due to dirt or dust in the zoom mechanism.
If you think you can handle disassembling the camera then grab a set of gentile screwdrivers and follow these instructions:
You will have to remove a few circuit boards in order to get to the zoom mechanism.
