I admit that I was initially very skeptical, lightning, to compatible with the i-TTL system Nikon and at the price, I ordered through Amazon, minimally more expensive but with better service if my fear should prove to be true. Then the mailman came with the flash. After unpacking first pleasantly surprised. Very valuable, inuative operation, all located within easy reach, very easy to use. Then first ausproberen, I thought, said and done. What can I say, with my D300, there is nothing to complain about, runs together with the internal and also with the SB-800. Then I have been tested with the wireless flash triggers YN-622N and YN-622 TX, everything goes perfectly. Clearly recommended.
