Fujifilm FinePix F40fd Manuel D’Utilisation

35

FinePix F40fd / FinePix F45fd 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).

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.

• 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.

• AF-assist illuminator does not fire in ,, ., , , 

, , 

or  

mode.

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

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