Focusing Manually - Sony a (alpha) DSLR-A100 Operating Instructions Manual

Focusing manually

When it is difficult to get the proper focus in auto focus mode, you can adjust the focus
manually.
1 Set the focus mode switch to MF*.
* MF: stands for Manual Focus.
2 Turn the focusing ring of the lens to achieve a sharp focus.
• In the case of a subject that can be focused in auto focus mode, the z indicator lights up in the viewfinder
when the focus is confirmed. When the wide focus frame is used, the center frame is used, and when the
local focus frame is used, the frame that is selected with the controller is used.
• To obtain steady exposure in manual focus mode, the camera uses the distance information to determine
the exposure. To improve the precision of the distance information, the camera resets the focal length to
(infinity) when the POWER switch is set to ON.
