I have a D300 and unfortunately I did as others the problem is that this flash does not work in the i-TTL. In manual mode, is to use the good and works well on camera control (entfeselt) via manual adjustment in flash menu. The data is transferred from the camera in the Sn-mode to flash .... but is still "manual" flashes. Too bad, the TTL flash works apparently only for the "Canon-variant" (with Canon camera). Would I buy it again but. If no spontaneous situations are taking pictures, you can bet with a little practice in manual mode good lighting effects that are normally difficult to achieve in the TTL.
