When Auto Focus Fails

Manual focusing using the focus mark

(Focus confirmation method)

With this camera, the focus mark lights in the viewfinder’s LCD when the picture is in focus. With the shutter release button half-pressed, turn the lens focusing ring to focus on the subject. When the subject is in focus, the focus mark lights in the viewfinder’s LCD.

If is lit in the viewfinder’s LCD, the camera is focused on a point behind the object. If is lit, the camera is focused on a point in front of the object.

The Auto Focus function requires contrast on the subject. Auto Focusing may fail to achieve accurate focus with certain subjects described below. In such cases, either switch to the manual focus mode and focus manually, or bring into focus an object at the same distance as the object you want to photograph, lock the focus using the focus lock mechanism, then take the picture. (see the following page)

In focus

Turn the focusing ring clockwise.

Turn the focusing ring counterclockwise.

Use the focus mark when taking photos in manual focus mode or using the M645 manual lens.

If you adjust focus using the focus mark with an M645 lens, make sure to open the aperture. You can use this function with a lens of f/5.6 aperture or higher.

You can set the camera so that only the focus mark is displayed. Custom settings (C-18 on page 94)
