Olympus Stylus Zoom 115 - Manual (Page 63)

The autofocus didn't work correctly. There are
some subjects that are difficult for the autofocus to
lock on. These include: glossy or reflective
surfaces, black objects, subjects behind glass or
wire mesh, flames and smoke, excessively bright
light within the picture area.
First focus on an object at the same distance
as the desired subject. Then aim at the desired
subject and release the shutter release button.
