Question about Canon EOS 40D Digital Camera
Hello, I have a Canon 40D. I used it yesterday and the auto-focus seemed to freeze. I'd press the shutter down halfway and it wouldn't take the picture. After I took the battery out, it seemed to fix the problem......but, I don't want it to happen again. Any answers? Thanks.

I too have the same auto focus issue. But the problem is intermittent.
Called Nikon today. They suggest:
- call when the camera is acting up
- be ready to give them the serial number
Apparently they are available 24 x 7 and will troubleshoot over the phone...

Things to check before you assume it is a mechanical issue-you can get vibration message if flash is disabled, be sure also that the macro mode is not enabled-this is very common on sony cameras to turn on by accident-flower button on camera will put in close up mode and you will get blur make sure no flower is present on lcd screen-if in macro press button on camera w/flower to turn off-also in menu you have continuous and monitor auto focus settings try changing one or the other and see what happens

Look on the left side of the lens. Make sure the button is on A for auto focus and not M for manual. OR not stuck in the middle. Hopefully that will solve the problem.
