    Hi guys,

    I'm new to flash photography and I'm just starting to explore it's creative possibilities. I just got 2 Nissin I40 units and I was wondering how to have one flash on camera triggering the other flash (I would like to be able to use it in TTL and manual). Will I need a wireless remote trigger or something?

    This was taken from their website (

    "Slave Mode
    i40 has a wireless remote flash system as a slave unit.
You can enjoy creative flash photography with multiple lightings from the various directions. There are 3 slave modes provided.

    Slave Digital (SD): i40 synchronizes to the pre-flash system. The master flash is to be set at TTL mode.
    Slave Film (SF): i40 synchronizes to the traditional single flash system. The master flash is to be set at manual mode.
    Wireless TTL
    i40 synchronizes to the wireless remote flash system. (*3) (*4)"

    Hi Rawfa,
    I am in the same boat and was hoping that someone would chime in here as I am considering either the Nissin i40 or the Phottix Mitros+ units.

    Basically, the i40 Nissin doesn't serve as a TTL master for flashes, but will do remote non-TTL manual triggering and the flash on the camera will also trigger the i40 flashes. The Sony 43 model (?) seems to offer the most as a TTL master/commander for remote TTL slaves.
