When you use Digital SLR cameras, functions will vary depending on the lens type and combinations of exposure modes, same as F5 and F100 group. (However, all TTL exposure functions will be the D-TTL (i-TTL) system). Exp.

[. . . ] Focus on the subject and set the camera's F-stop, using the exposure calculated by the formula shown below: F-stop = Guide Number (G. N. ) ÷ Flash to Subject Distance (m) 4. After the flash is fully charged, press he Shutter Release button to take the picture. Guide Number will change according to the Zoom Head position, (seechart. 2). Guide Number will also change according to film speed (ISO), (seechart. 3). [. . . ]
