Auto Focus Not Working

Hi, I have my Canon EOS 450D Camera for about 9 months now and I greatly enjoy using it but as of now I encountered a problem regarding the AFfunction, it does not respond Auto Focus especially when I'm at AV mode, so basically the pictures are all blurred so I'm switching to MF that makes it hard for me to use.. Whats the problem regarding my Camera?
Thanks in advance ^_^

I had a same problem, Auto Focus works in all the Basic modes but it did not work in Advanced and Manual modes.  After couple of hours of frustration I found the solution. It worked for me, I hope it will work for you too.
Follow step by step instructions. Start the Camera
Go to M (Manual Mode) Press Menu Button Go to 6-th Tab Custom Functions (C.Fn) Select Clear settings Select Clear all Custom Func. (C.Fn)
This should fix your problem
Go back to shooting more and try your Auto Focus

There are several possibilities. Start with these first 2 steps:

1) If you have more than one lens, try a different lens. If the problem persists with different lenses, then the problem is in the camera. If the problem goes away with a different lens, then the problem is in the lens.

2) Clean the contacts between the lens and camera. Gently rub the contacts with a clean pencil eraser, and hold the item with the contacts facing down so that the eraser debris falls onto the table, not into the lens or camera.

If this doesn't fix the problem then it is internal - either in the lens or camera. Refer to step 1 to test to see which it is. Then you need to send the appropriate item into Canon for cleaning and repair. Canon may request that you send both the camera and lens, so call them before you send the item in for repair.

Auto Focus won't work


Another cause of auto focus failure is the circuit connecting the moving parts inside the lens. These "Flexi circuits" move with the lens components and wear out after a while. They are cheap enough to find on ebay and easy to replace.

Auto focus problem


Could be dirty contacts. Remove the lens and clean the contacts on the body and the lens where they meet with a cotton swab lightly dampened with rubbing alcohol.

My Canon EOS 450D shows busy while trying to click on AF auto mode and it does not click at all.


There are several contributing factors to this problem and I'll try to list a few that may be the cause.
All Canon EOS camera auto focus modes us contrast to focus this means simply that no contrast there is no focus. There is a small green dot in the lower right corner of the viewfinder that will come on and stay on solid when auto focus as been achieved. By default the shutter will not operate "click" if auto focus has not been made.

Here are a few examples of where auto focus will ether search (focus back and forth) or fail completely.

A solid painted wall, glass between the camera and subject, mirror, chrome, any large body of water, clear sky. Another place you wouldn't expect is clear skin in your subjects face or body.

Cameras with multiple focus points and set to other then the middle will have a problem if the photographer is still attempting to use the center focus point.

Look for the green dot in the lower right corner of the viewfinder that's your focus confirmation.

You need to read the manual. Use the Custom function(7 I think) to enable Live View. Now when you use the SET button you can see the image on your LCD. Use * button to use Auto Focus
