Autofocus not working. (18-55mm lens)

Hello,

 

The autofocus on my Canon 18-55mm is malfunctioning and I'm afraid it may be broken.

All the internet research I've done points to issues electronic, but I believe this to be mechanical simply because of the noise it makes. With the lens set to AF, it does nothing, but makes a slight whirring sounds as if the camera is trying to, but can't focus the lens. In MF, turning the focus ring makes soft clicking sounds.

The autofocus works fine on the other lens I have.

The lens has not been dropped. I take really, REALY good care of my stuff!  Any other recommendations or bits of advice are much appreciated!

Hi marcosochoa!

 

amphoto1 makes some very valid points, and it does sound like it could  be the motor in the lens. We have found that sometimes we're able to remedy this without a costly repair, but it is a multi-stepped process.

 

Try this:

  1. Take the lens off of your camera.
  2. Put the lens in MF mode.
  3. Twist the FOCUS ring (the tip of the lens) all the way to one side (extend it). You may hear a click noise or two, this is good, but don't FORCE the lens.
  4. Twist the FOCUS ring all the way to the opposite side (retract it). Again, you may hear a couple of clicking noises. What we hope is happening is the focusing motor being put back into its proper place.
  5. Put the lens back on the camera.
  6. Put the lens in AF mode.
  7. Turn the camera on.
  8. Put the camera in AUTO or P mode.
  9. Take a test photo.
  10. Profit.

Hopefully this solves your problems, and you never have to worry about it again! With my personal lenses that are not USM or STM, I always store and transport them with the AF/MF switch in the MF position. This disengages the focusing motor and prevents any accidental damage to the auto focusing motor.

Hi Stephen,

I did try some of the suggestions in this thread before creating a post, but unfortunately they did not work for me. I also tried one more time after your suggestion here, but it still did not do anything for me. I've seen that some others in this thread have a problem where their autofocus does not work at all, but as stated above (and in the reply on page 2 by Martmcin as well) my autofocus works 50% (works one way but not the other).

Could it still be that the focusing motor has to be put back into its proper place in my case here?

Hi Steria!

 

It could be that the focusing motor needs to be re-aligned (usually the steps provided do that trick), or it could be that the focusing assembly has been damaged. If the assembly is damaged, it's time to look into repair or replacement of the lens. Smiley Sad

I have and I don't have a solution 😞 did you find any advise or solution to this?

Did you try the chiropractic solution listed very early in the thread?

Hi,

 

Has anyone experienced this issue but only focussing one way? My lens will focus on a subject further away but refuses to focus back to nearer subjects. Its such a pain having to set to manual in order to reset the focus to near everytime!



I have experience the same, it only focus in one direction and I don't have a solution 😞

Try this carefully........

  1. Take the lens off of your camera.
  2. Put the lens in MF mode.
  3. Twist the FOCUS ring (the tip of the lens) all the way to one side (extend it). You may hear a click noise or two, this is good, but don't FORCE the lens.
  4. Twist the FOCUS ring all the way to the opposite side (retract it). Again, you may hear a couple of clicking noises. What we hope is happening is the focusing motor being put back into its proper place.
  5. Put the lens back on the camera.
  6. Put the lens in AF mode.
  7. Turn the camera on.
  8. Put the camera in AUTO or P mode.
  9. Take a test photo.

The problem that the posted procedure resolves is unjamming lens motors that have become stuck.  This situation usually arises when people attempt to turn the focus ring when the lens switch is in the "AF", auto focus, position. When the lens switch is in the "MF", manual focus, position, the focusing motors are disengaged from the focusing elements. 

 

It is easy for beginners to mistakenly turn the focus ring, when the lens is "AF" mode.  I know that I have done it before.  It is all too easy to turn the focus ring, instead of the zoom ring.

 

As far as attempting the posted procedure, do make sure that you lens exhibits the exact symptoms they describe.  Read the other posts by people who said they initially tried it, and failed.  But, then built up some courage and applied more force on the lens, and it worked.

 

If you are in doubt, let a professional in camera shop take a look at the lens.  Print out the procedure and let the pro see it.

My focus ring just turns and the lens doesn't move, neither auto or manual mode.

Your issue sounds like it could be more severe than the issue this thread tries to address.  I suggest contact Canon Support for professional guidance.  Most of the 18-55mm lenses that are included in many Rebel Camera Kits are relatively inexpensive, and most will usually cost more to repair than to replace

 

But, not all 18-55mm lenses are created equally, as there have been new and improved versions of the lens released over the years.  Again, contacting Canon Support at 1-800-OK-CANON is your best course of action.
