My Canon digital rebel will not autofocus correctly. My camera has 7 points autofocus, but it will only autofocus on the far right point. All other points are not used. I have had the camera for 14 months and the problem just began. If I want to focus on anything in the left to center of the field of vision, I cannot do it. However, the lens focuses manually very well. Why won't my camera focus on other points than the far right one?


I had this problem awhile ago - you must have accidently adjusted the focal area - it is sooooo easy to do without realising it. Here is what I was told:**************************Most likely, you have changed the AF point, which onl ... Canon Rebel XT / EOS 350D Digital Camera

Hi there i have a auto focus problem. i used mt 50D for the first time on saturday, after about 100 shots Err99 appeared, i turned the camera off and took the battery out an the error message never occured again, however since then the camera will not auto focus correctly with my 17-40 IS lens. the lens has worked perfectly on my 20D for the past couple of years.

Hi, I've a Sigma 28-105mm aspherical 3.5-5.6 lens. Auto focus does not engage. I can hear the motor trying, but the ring does not turn. When I switch to manual focus, I can turn the ring to focus manually, but I still hear the motor trying to use autofocus. Additionally, sometimes the shutter will not fire in manual focus while the motor is still searching. I've cleaned the contacts, but no joy. I suspect a faulty switch, but that doesn't completely explain the autofocus not engaging. I am


Well, I think you have at least one problem pinpointed, in that I suspect the focusing ring is jammed, and cannot rotate with the electromagnet signals. The other problem might be a faulty auto/manual switch. Of course, check for oxidation and e ... Digital Cameras

Canon EOS Rebel XT with EFS 18-55mm lens. Trouble-free for two years. During a weekend of lots of use, suddenly the camera would not autofocus. Switching to manual focus, the camera worked. Then it started working okay in autofocus. Later that day quit altogether. (Would not release shutter even in manual mode.) Removed the lens and cleaned the contacts on both lens and camera, started working okay but only temporary. Went through several cycles of this over the weekend, so I'm not sure

Autofocus off How do I adjust the autofocus feature on the device. I can see when the lens moves, it passes through the focus point. I could lay out a tape measure to see where it is in focus if necessary.

Hi I have a Nikon d200 and with a Sigma 50mm Macro AF 2.8. The lens is a few years old. and it's the first time I tride it on the d200. I can't get the autofocus working, is the lens not compatibel withe the camera? or is there some adjustment on the camera I can do. The lens does not have internal focus motor. it's adjusted by a smal screw in the conction of the lens. Any ideas?


I'm assuming this lens worked on another Nikon camera before and that the lens mount is for Nikon cameras. Make sure the aperture ring is set to "A". Clean the contacts on the lens and camera body where they meet with a cotton swab lightly dampened w ... Nikon D200 Digital Camera

Hello I bought 1 month ago lens 50mm 1.4 in usa, but now i am living in London. As I know there is international warranty on canon products not for body. But they told me I should pay fo that Labour: £50.00 plus VAT Parts: £35.09 plus VAT This estimate is for a replacement of barrel, track and scale, set up and recalibration, relubrication of the focus system and check and clean. The lens has received impact damage its Fixationuk.com so let me know if I have to pay or send it back to US


You would still have to pay for the repairs in the US. Impact damage is not covered by the warranty. See this ... Canon Digital Cameras

Error message my nikon D -80 is flahing an error message. When i try to take a photograph i hear it cycle, but nothing is taken. The automatic focus does not work.

Nothing worked and the same messages is displayed when i turn the camera on. Any advic

The image in the viewfinder is out of focus. The autofocus feature goes back and fourth and when it stops it is usually out of focus. During this process it makes a squeaky sound. I have reset the camera, reset the lens (AF S Nikkor), and tried the camera in all of its shooting modes.


Either the lens itself is faulty or it is dirty and needs to be disassembled and blown out with a can of Airduster. ... Nikon D40x Digital Camera

I was using my Nikon D40 at son's baseball game with the 55-200 mm lens & was too close to the fence when zooming since it tapped the fence. Now it makes a squeaky noise when trying to auto focus. It will not take a pic on auto focus but will focus and if I flip the A / M switch on the lens itself over to M it will take a pic.It will take pics fine with the 18 - 55 mm lens.

Focus malfunction I have been shooting with my D70 for a little over a year now with absolutely no problems. I shot with it last weekend with no problems. However, yesterady when I took my camera out to use it I realized that my autofocus single area option won't let me change from one focus area point to another. It is stuck on the center focus area. Even stranger when I tested the autofocus on the closest subject mode it is capable of locking on each of the five focus points. Does anybody know


THere is a little switch on the back of the camera, just under the area selection Dpad. Make sure it is not in the 'L' setting. This locks the selected autofocus area. ... Nikon D70 Digital Camera

Trouble focusing I am using my D60 with a 18-55mm lens, i have it set on auto its been working fine until recently when it is unable able to focus when i press on the release button. All that seems to happen is the lens keep going in and out where it is trying to focus. I have removed the lens and checked the contact but its still not working help!!!


Not too many things that can do this are simple, but here are a few you can check. First, make sure you aren't too close for the lens to focus. For the 18-55, that's only about 5" from the front of the lens, so I doubt this is the problem. \ ... Nikon D60 Digital Camera

Won't Focus I have had my Canon Powershot SD1000 for about 9 months now. I have had problems with the lens error and it getting stuck but have always been able to get it to work eventually. I had another bout with the lens getting stuck, was able to get it unstuck but now it won't focus at all. Normally I press the shutter down half way to get it to focus on my subject, but now it simply won't focus. I'm wondering if maybe my settings are off, or if it's an internal problem. Any suggestions


You still have a bad lens the internal focus gear is out of alignment. or is offset. a repaired or new lens is required. Sorry :( ... Canon PowerShot SD1000 Digital Camera

My D80 was purchased in April 2008 along with the Nikkor 18-200mm VR zoom lens. The camera and lens worked flawlesly until this past week end. The cameral stopped focusing in auto mode with no warning. I did hear a whining noise when I tried a Tamron 11-18mm wide angle lens. The auto focus did not work with that lens either.

Good Morning I went hiking in broad daylight this past weekend and the autofocus would not work. I have a Canon 40D with a TAmron 18-270. I used av, tv, p, m and auto and I could not autofocus the camera. All I could do is to switch to manual focus to get it to work. When the lens was set to AF all you could is hear is it racking back and forth tying to focus. VERY FRUSTRATING.. Any ideas of what it may be or a setting I might have set accidentally. Any help is appreciated. Bob

First thing I would do is clean the contacts on the camera and the lens. Do you have this issue with another lens, if not then it is not the camera. If you do then recheck the lens. You could call Nikon Digital as well at 1-800-645-6689 ... Nikon D80 Digital Camera with 18-135mm Lens

My Canon Rebel XTi has repeatedly had the Err99 message pop up, and it's to the point that it happens, at minimum, every 4-5 shots I take.
