Hi, bros,

I would like to use slave flash with my Panasonic LX1 cos the flash output of the LX1 is not high enough. I have a slave sensor, a flash and a Hakuba camera bracket.

The problem is I find that the LX1 emitts a "pre-flash" right before the "main flash". I guess the pre-flash is for measuring the right exposure but this just trigger the slave flash and make it flash "too early".

I cannot turn off that "pre-flash" and do you have any trick to overcome this problem?

Thanks a lot.

yualbert

I think I have to get the following device to overcome the problem.

http://www.adorama.com/WNHSD.html

The feature is "Since ordinary slave units will not work with most digital cameras (because these cameras use a very rapid series of pre-flashes, that trigger the slave prematurely), Wein is now offering the Digital line of slaves. A typical slave unit will fire on the pre-flash it senses while the digital camera captures the image on the last flash. These slave units are specially designed to only be triggered by the correct flash sensed by their built-in optical sensor and circuitry, thus solving the digital camera flash problem.

Attach this slave directly to foot of any shoe-mount flash for direct connection, or connect a standard PC cord to the side mounted PC terminal. Features a standard foot on the bottom and 1/4-20" standard tripod thread."

:wink:

Metz SCA-3083 digital can do the same thing but it is only for Metz flashes.

The "SCA-3083 digital" enables the user to select any of the slave modes 1, 2 or 3, depending on the given camera.
1. Slave trigger function without preflash suppression
2. Slave trigger function with preflash suppression
3. Slave trigger function with extended preflash suppression


Make sure the one you found from Adorama will work with LX1 as the preflash behaviors are different for different digital cameras.
