Canon 400D. Autofocus problem

\015 My 400D has just developed an autofocus problem. \015\012When I press the shutter button half way to activate the autofocus, it is constantly stuttering - the lens is moving left and right rapidly - as if it is confused about what to focus on.\015\012It is not focusing in and out like it would if you point into the sky for example, it is moving fractionally in and out just a couple of millimeters each way, and I would imagine it's not doing the drive any good.\015\012I have tried 2 different lenses with the same results, so presume it is the camera where the fault lies. Could it be a dirty sensor?\015\012\015\012Any help will be much appreciated.\015\012\015\012Mal B.\015

Answers :

(facing the LCD screen towards you, as if you're going to take a photo) there's a button in the upper right-hand corner that will allow
you to AF to a certain point (9-pts total) or the center, or all 9-points, maybe you have it set to one point and it's off center??
definitely sounds like a camera setting probelm

I have a Canon EOS 1000D, and I've had it for almost 4 years. Recently i started having problems with both my lenses. Autofocus works but through the everything appears blurry when "focuses" and thus I can't use manual focus anymore.

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

No power I purchased a Canon 400D about a year ago and shortly afterwards the camera suddenly gave up on me. I took a couple of photos and then nothing.

I was going to take the camera in to a service centre a few weeks later for repairs but when I switched the cameraon again, the problem seemed to have disappeared. Since then I have been taking photos w
