Using the

Camera

Subjects not suitable for autofocus

FinePix F40fd / FinePix F45fd / FinePix F47fd uses a high-
precision autofocusing mechanism. However, it may have
difficulty focusing on the following:

• Subjects photographed through glass
• Subjects that do not reflect well, such as hair or fur
• Subjects with no substance, such as smoke or flames
• Dark subjects
• Subjects with little or no contrast between the subject and

the background (such as subjects dressed in the same color
as the background)

• Shots where another high-contrast object (not the subject) is

close to the AF frame and is either closer or further away
than your subject (such as a shot of someone against a
background with strongly contrasting elements)

For such subjects use AF/AE lock (

➝p.34).

AF-assist illuminator

Use this illuminator to focus on the subject in dimly lit
conditions.
When pressing the shutter button down halfway, the
camera fires the AF-assist illuminator (white) while
focusing on your subject.

MEMO

• Even when the AF-assist illuminator fires, the camera

may have difficulty focusing in some conditions.

• Even though there is no danger to safety, do not expose

it directly in someone’s eyes.

• See p.107 for information on turning the AF-assist

illuminator off.

• When using the AF-assist illuminator in Macro mode,

the camera may have difficulty focusing to take close-
up shots.
