    Hi,

    I have a few questions regarding the YS-D1 strobe :

    1. Will it be ok to run the YS-D1 with 1.6 rechargeable NiZn batteries ?
    Will it provide improved performance ?

    2. has the YS-D1 been tested with Nikon's P7000 ? Are there known issues with P7000 (I know it's not in the certified camera's list).

    3. Is it Ok to have two YS-D1 connected to the camera housing and both setup as DS-TTL II ?

    4. What's the technical differences between DS-TTL and DS-TTL slave (blue led)
    {I know that in the TTL slave mode the exposure compensation doesn't work, my question is which use-case requires the use of this mode rather than TTL with zero compensation}

    Thanks !

    Meni,

    Regarding DS-TTL II/DS-TTL slave.

    Pre YS-D1's DS-TTL (via fiber optic cable), you can adjust the exposure, but it was only into the minus position, and in some numeric instead of EV steps? So the only difference between DS-TTL & DS-TTL II is the steps being in EV and having the + EV positions? Or does the camera actually knows that there is flash exposure compensation taking place?

    Is new DS-TTL slave just the old DS-TTL via fiber optics cable?
