FZ150 / Pre-Flash?
The pre-flash that I'm used to and would like to know if I can get it on the FZ150 is where you press a button and it preflashes and remembers for the reading for the n number of flash shots as long as the camera has been idle for more than say 20 seconds.
BTW, I have found red-eye with the FZ150 to be rare and minimal even in regular flash, I never turned on the red-eye mode.
Check out page 68 of the manual. If you set the flash to automatic red-eye reduction it will do a preflash (to reduce your subjects pupils) then open the shutter and take the flash picture.
