EF-S 10-22mm Canon not working in AF correct

[AlanRhodes]

My EF-S 10-22mm Canon lens in AF mode is mostly taking out of focus pictures. I tried the basic clean the post but still keeps center of image out of focus. All my other AF lens work fine. Base is a Canon 60D. I have had lens new for about 5 years with no issues until now.

Any suggestions?

And the lens does this on both camera bodies?  Yes?  The lens is bad.  It needs to be evaluated by Canon service to see if repair is feasible.  Cost may be prohibitive.

Yes does same but not always same part of image is blurred but 90% shots are bad. Rather disappointed if this ~$600 lens is bad and not sure I want to rebuy same lens if this is the quality I get. Any recommendation on a good all around portrait and landscape lens as this was my go to lens for family shots, car shows and landscape shots. I had alway bought Canon bodies for the lens but starting to rethink this now.

Thank you

Well all is not lost yet.  Have it evaluated.

But remember anything made by the hand of Man can and will eventualy fail.  

This is a good lens and is probably better than anything else in it's focal length.  There are offerings from the 3rd party world but they will be no better QA wise or construction wise.  I have the very same lens and I also like it very much.

Your lens needs to go in for evaluation and repair. It looks like a badly decentered lens element to me. That requires disassembly and repair. No amount of fooling around with it or cleaning the contacts will make it work right.

It appears not to be a fault of the camera itself, especially if your other lenses focus correctly. In fact it's not really the auto focus system at fault, when part of an image is out of focus like that, while the other part (in the same plane of focus) is sharp. It's gotta be an optical fault within the lens.

Probably the reason it appeared to work differently ("better", but still not right) on another camera is because it was set up to use a smaller aperture, giving more depth of field that covered up some of the fault of the lens.

If, as you say, 90% of the images are bad... that implies the other 10% are okay. Check those and see if a smaller (higher f-number like 11, 16 or 22) is being used, rendering more depth of field. Otherwise, it might be a loose element or focusing group, that's finding focus one out of ten times, but failing the rest.

No matter, really. The lens needs to go in for evaluation and, if economically sensible, repair.

OK thank you. Looks like I need to send lens in. Problem in I have my sons graduation party this Saturday. Is cost to repair close to if I go get the same lens new? Or any recommendation on a different lens to go buy for un posed family party shots?

Although the 10-22mm is a good lens I would prefer the EF 17-40mm f4 L.  This is just my personal prefference but I no longer buy any EF-S glass.  There has to be a very goood reason to break that rule for me.  There is no "L" made in EF-S for instance.

Any thoughts on the EF-S 17-55 f2.8 IS has a all around replacement for my 10-22mm?

[ebiggs1]

You already know my answer.

The image certainly looks like one of the lens elements is out of collimation -- possibly not perpendicular to the lens axis (as if it's come loose). This can also be caused by a sensor which isn't shimmed (there are adjustment screws inside the camera so that service can shim the sensor plane) except that since the problem follows the lens, your issue is certainly with the lens.

The EF-S 10-22 has a good reputation so I doubt you run into this with a different copy of the same lens.

As for the 17-55... that's a completely different lens. The 10-22 is an ultra-wide. The 17-55 is a standard zoom (ranging from slight wide angle through normal and into a slight telephoto). The main advantage of the 17-55 is that it can provide f/2.8 focal ratio at any focal length in it's range (the kit lens, for example, can only offer f/3.5 at it's widest angle, and reduces aperture to f/5.6 as you zoom in.) These two lenses have very little over-lap so you can't really call one a substitute for the other... but the 17-55 is a better general use lens.

Thank you all. I am going to send in the EF-S 10-22 to Canon and hope the cost is not too high to repair an already costly lens. I am buying a Tamron AF 17-50 mm F/2.8 SP XR Di II VC to have for this weekend sons grad party since my go to  Canon lens for this type of family shots is out of serveice. 

Feeling a little burned on the Canon lens, I paided the higher lens cost for the Canon expecting longer service and quality then I received. But since I am a novice I am going to give Tamron a try for my future business this go around.
