TTL Auto Flash 
Mode: For F4-Series, F-801/N8008 and F-801s/N8008s Users
Chapter

Choosing A Flash Method
The SB-25 enables you to perform the following flash meth-
ods. They are described in detail on pages 10 to 13.
• Matrix Balanced Fill-Flash
• Center-Weighted Fill-Flash
• Spot Fill-Flash (not available with the F4-Series or
F-801/N8008)
• Standard TTL Flash
Use the chart at right to confirm which flash method you
will perform with your camera, the lens in use and the
metering system set on the camera. In most cases, the
lens/meter combination determines the flash method. In
other cases, you may have to switch metering systems,
change lenses, or both.
By using the SB-25’s 
button, you can also choose
Standard TTL Flash, regardless of lens type.
For practice, read “Set Up and Practice,” from page 42
on.
