As with the previous speaker, the lightning jumping not always the same with. It probably seems to be a function that is not evident to me a standby / wakeup. Continuous shooting is possible only to a limited - partly solves the flash after 2 images no longer - after 4 images has always been final. (There have been various batteries tested)
The slave / master mode does not work with my D5000 - Unrated.
The instructions I do not find particularly clear!
I like the manual trigger very good. Otherwise, the device does what it should - flashing / illumination - The images are good!
