Re: Autofocus not working. (18-55mm lens)

Crystal's advice (page 1 of this thread) to "just pull" worked perfectly.  Thank you!

 

I have the IS II version of this lens.

 

I didn't pull hard enough the first time.  It took a solidly "medium" amount of force.

 

In retrospect, I believe that before the lens's "chiropractic adjustment" the lens didn't track right with manual focus slew.  By that I mean that in manual focus mode, when twisting from focus extent to extent the lens simply racked in one direction.  After the adjustment I was reminded how the lens normally works - at one extent of focus ring travel the lens is out a bit, as you focus it retracts, then at about mid-focus-adjustment it starts racking out again, finishing the focus travel sticking out again.

 

So if your lens is having trouble, and doesn't do the out-in-out behavior, this "pull on the end" technique may be just the trick.

Like others, my AF does not work. I tried all the fixes but nothing helps. It will AF when in the "Live View" mode but it is so slow so not really useful for my type of photography. Bummer!

If the lens can autofocus in LIve View, then there is nothing wrong with the lens.  The advice on this thread apply to situations where the lens does not focus, at all.  It seems dead in the water, because it is.

 

What are you trying to photograph?  What camera body are you using?  Is your lens and “STM” lens?  What position is the shooting mode dial in?

Live View mode uses an entirely separate focusing system from viewfinder focusing.  Be aware that you can encounter low light situations where the camera will not focus.  If you are too close to the subject, the camera will not focus.  If there is insufficient contrasting lines under the active AF point, then the camera will not focus.

If you using One Shot mode, then the camera must acquire a focus lock before it will take a picture.  Switch the camera to “P” mode, and then change the AF mode to “Ai Servo”.  The camera should now take a picture whenever you press the shutter, assuming the camera is operating with the factory default behaviors.  The camera can be reset to factory defaults in the menus.

I'd given up hope, and tried this several times until I understood the description!  SUDDENLY my auto focus works again!

I'm thrilled!
