Canon EOS 5D instruction manual 117, Live Mode and LiveuFace Detection Mode Notes, AF operation

Using AF to FocusN

If the focus is way off, face detection will not be possible. If the lens enables manual focusing even while the lens focus switch is set to <f>, turn the focusing ring to attain rough focus. The face will then be detected and <p> will be displayed.

An object other than a human face might be detected as a face. Face detection will not work if the face is very small or large in the picture, too bright or too dark, titled horizontally or diagonally, or partially hidden.

The <p> focusing frame might cover only part of the face.

When you press <9> straight down, it will switch to the Live mode (p.115). You can tilt the <9> to switch to another AF point. If you press <9> straight down again, it will switch back to Liveu(face detection) mode.

Since AF is not possible with a face detected near the edge of the picture, the <p> will be grayed out. Then if you press the <p> button, the center AF point <> will be used to focus.

Live Mode and Liveu(Face Detection) Mode Notes

AF operation

Focusing will take slightly longer.

Even when focus has been achieved, pressing the <p> button will focus again.

The image brightness may change during and after the AF operation.

If the image flickers, making it difficult to focus, stop and resume the Live View shooting under the actual light source to be used. Check that the flickering has stopped, then autofocus.

If you press the <u> button in the Live mode, the AF point area will be magnified. If it is difficult to focus in the magnified view, return to the normal view and autofocus. Note that the AF speed may differ between the normal and magnified views.

If you autofocus in the Live mode’s normal view and then magnify the image, the focus might be off.

In the Liveumode, pressing the <u> button will not magnify the image.
