20 Most Recent Canon EF-S 18-55mm f/3.5-5.6 USN Lens Questions & Answers


Pulling gently on the focus ring worked for us. Exactly what the Dr. ordered. Slight pop, maybe 1/16" movement, and the lens is working again!

Try cleaning the electronic contacts on the lens and camera.

I see this same problem occuring all over the internet on Canon lenses. Autofocus not working any longer. For some stupid reason the lense will lock up and quit autofocus while other lenses will work fine. A light pull on the lense focus ring away from the camera body will give a noticable pop or click which unlocks the jammed lense. Try it if you are having troubles with your autofocus. This is a very common problem and worth giving it a try.

If you have another lens, try that on the camera to determine if the damage is the lens or the camera. If the lens is damaged, just buy a new one, I would not trust the elements to focus true on a lens that has had an impact severe enough to cause this problem. As this is the standard lens that ships with most Canon Packages, you can likely find a cheap one online.

Replace the broken ribbon cable in the lens

You'll probably need a professional repair. Compare the cost of repair with the cost of replacement. On that lens it could be about the same.

If the lens will focus on manual focus but won;t on auto focus you may have a ribbon connector failure in the lens. This ribbon continually flexis as the lens moves in and out. Over time this can break and will probably need to be replaced. All good camera repair shop should be able to do this for you and this remady is one of the cheaper repairs to photographic equipment

Probably a broken ribbon cable connector

Canon EF-S... | Answered on Mar 25, 2016


Hi

this is because flex cable damage. Lens does not know exact position of focusing lens, so it fails to work in AF mode. Problem is fixable but not DIY. Should cost around 40USD (35Eur).

If the focus works OK in manual focus and you are getting problems with auto focus you may have a broken or worn ribbon in the lens.

If you flip the M/AF switch on the side of the lens and the then the camera takes a photo, Then the focus drive gears are damaged in the lens and needs repair,

Take it to a camera shop.

Canon EF-S... | Answered on Aug 29, 2014


I'd say yes as the replacement cost for this lens would probably exceed the repair cost

The symptoms you've described are that of the possibility of a broken ribbon cable. As the second lens works on both cameras then the strong possibility is that it is the lens at fault and not the camera. Another quick test would be to put the 'faulty' lens on manual focus and check that it will focus in that mode. To replace a ribbon cable is not too expensive. With all items of modern photography they have intricate electronic circuitry and the definitive problem will only be known once a competent repairman takes the lens apart, but I think you've worked out the problem.

It may be that the ribbon connector has broken in the lens.

Canon EF-S... | Answered on Aug 03, 2014


If the camera is used you may have a problem with the seller. Before jumping into conclusions however read your manual for your solution or simply search youtube for a help video. Hopefully this helped.

Canon EF-S... | Answered on Feb 15, 2014


Since it is a brand new camera, take it back to the shop where you bought it. There isn't really anything you can do.
