FV Lock This feature is used to lock flash output, allowing photographs to be recomposed without changing the flash level and ensuring that flash output is appropriate to the subject even when the subject is not positioned in the center of the frame. Flash output is adjusted automatically for any changes in ISO sensitivity and aperture. To use FV lock: 1 Assign FV lock to a camera control. Select FV lock as the "press" option for Custom Setting f4 (Assign Fn button, 0 343), f5 (Assign preview button, 0 349), or f6 (Assign AE-L/ AF-L button, 0 349). 2 Press the flash pop-up button. The built-in flash will pop up and begin charging. 3 Focus. Position the subject in the center of the frame and press the shutter-release button halfway to focus. Flash pop-up button 198
