Focus these difficult subjects as follows:

Low-light situation (ii)

Subjects with objects in front of them (iii)

1Make the following adjustments, as needed.

With low contrast subjects, focus on a substitute subject at the same distance from the camera as your main subject, then recompose the picture using the focus lock function.

With horizontal patterns, there is no problem when using a lens with a maximum aperture of f/2.8 or larger (except the EF50mm f/2.5 Compact Macro or EF28-80mm f/2.8-4L) because the camera’s central cross-sensor activates to detect horizontal lines. When using a lens with a maximum aperture smaller than f/2.8, use the focusing points other than the center as these have vertical sensors. Focus the subject, then recompose the picture using the focus lock function.

With vertical patterns, use the center focusing point which has a horizontal sensor, focus the subject, then recompose the picture using the focus lock function.

2Set the lens’ Focus Mode switch to (M) and manually focus the subject. (Refer to the section on “Manual Focusing” on the next page for more information.)
