Canon 60D Will NOT focus! Help!

CarsNoHomo 155 100 September 12, 2011 at 10:18 PM
Loaned my camera to a friend over the weekend, saw his pictures and his last pictures look to be in focus, but now I turn it on and it's not wanting to focus.

-On any picture mode, including fully automatic, AF will never focus. The lens tries to focus, then settles on something blurry like it found its focus
-AF and IS buttons have been turned on/off to see if anything changes
-MANUAL focus will also *not* work in any picture mode regardless of AF switch position
-When I go to video mode, I am able to focus the camera manually. AF also works but seems very slow to focus even with a lot of light.

Camera is 1 month old, with a used Canon 18-135mm lens, which was purchased from a professional photographer. I am guessing he took very many pictures with it, and perhaps the motor started dying so he decided to sell it off. However I do not understand why it would focus in video mode and not any picture mode.

What could the causes be?

what do you mean manual focus won't work? does changing the switch from AF to MF not disengage the motor?

Have you tried a different lens? Have you tried reseating the lens?

It could be the lens and not the camera. The focusing motor is in the lens. Can you really not focus in manual mode? It sounds like it may have been dropped. Try another lens and if you can get your hands on another camera body, try this lens on that body. You can send it in to canon or take it to a repair facility and they can diagnose the problem. It may be cheaper than a new body or lens. They are good at repairing damage, but sometimes costly if the problem is big enough.

Does the focus ring turn in manual focus mode? When you turn it does it not find focus?

It sounds like a lens issue. Something isn't moving in there. I'll bet it was dropped.

I agree on both fronts. It is possible it could be something in the body too but its less likely. Get your friend to fess up, this is why I also dont generally lend expensive things to people. Reset your custom functions to factory default settings and try another lens. If you have a local camera shot they might be able to do a free diagnostic, but if the body needs repair I would recommend sending it direct to canon.

What I don't understand is that you say it can't manual focus. If you turn the focusing ring, you can't get the image in sharp focus? That's got to be a bad lens.

but if it does "focus for video", shouldn't it be the exact same for stills?

or if it moves with auto-focus, but just doesn't stop at the right spot, isn't that a body focus issue (not reading when to stop changing the focus because it's set?)

I would say you can't be 100% sure it's just the lens without trying it first

I noticed that, too. But if moving the focus ring really won't focus the image, either the lens or the photographer is broken.

OP, which AF mode are you using? AI Servo, AI Focus or One Shot? Does it say "M Focus" on the top screen?

Which AF point are you using? A single point or letting the camera choose the point?

Have you tried to clear all camera settings?

Which button are you pressing to try to focus? The shutter button? Check to see if Custom Function IV-1 was changed.

What do you mean that manual focus will not work?

Took a picture and it was fine but still completely blurry in the viewfinder, turns out it was the viewfinder adjustment/diopter LMAO I was soo ready to take it to the camera shop too, glad I saved myself the embarassment.

But yeah, the motor, I know the 18-135mm isn't a particularly fast AF lens, does still seem slow compared to when I first got the lens. How often do these things die out? Any way that I can check the number of shutter clicks on just the lens?

The diopter was my first thought until you started talking about pics out of focus...

Whew! That could have been a big repair bill - glad it was something simple.

Also, there is no such things as shutter clicks on a lens - the shutter is in the camera body. On most Canon lenses you can determine the manufactured date based on the serial number, but that's about all the info you'll get from a lens. The focus motor may slow down over time, but unless you got a defective lens (heh or unless someone dropped it or damaged it) I'd imagine it would be years before anything like that happens.

Don't worry, we've got PLENTY of embarrassment to hand out right here. Big Grin Big Grin

But I should have caught that, so I'm embarrassed, too. I use the diopter feature a lot. It's a great thing for my middle-aged eyes. But you should have noticed that the viewfinder display (aperture, shutter speed, etc) was also blurry.
