To a thread about a suspected issue with the Nissin speedlight.
I have just received my Nikon SB700 and guess what !!! IT DOES EXACTLY THE SAME THING.
This can only mean that the Nissin does NOT have an issue arising from it being a third party flash unit. So IGNORE anything you read that says otherwise.
I have spent a fair bit on my Nikon flash thinking I dont want compatability issues with my camera, and I wish someone with a Nikon speedlight had picked up on my thread and warned me that the Nikon is the same but alas it was missed.
Any how the Nikon unit is the real deal, but I would say that now I have spent hard earned cash on it. If you want a just as good to use flash for half the money then deffo go for the Nissin unit, cus there aint anything wrong with it.
