I have just bought the Nissin Di866 flashgun. I notice my in built flash fires no matter how I set it in commander mode. I followed some online video to set-up the camera and flashgun to use it wireless, but I don't want my built in flash to affect the exposure.
my setting in the D90 commander mode
built in flash -- --
Group A TTL 0.0
Group B -- --
setting on flash
-set it to remote
When zoom my lens, the flashgun does automatically adjust the zoom range. However, the built in flash fires whenever i press the shutter and of course the flashgun fires as well.
From what I read from internet, the built in flash won't be active if i set it to "--". It doesn't happen to me, it fires every time... :(
is it normal ? is there a way to deactivate the built in flash and only the wireless flashgun fires?
