I use it on a D300s and D3100. Made its dissemination work. Occasione still a small loss of power of the flash and sets a tone a little colder to the scene unlike other broadcasters such as Lumiquest that have warm tones.
The assembly is very easy. As with all plastic, must be operated while gently.
This diffuser is now part of my mop kit for my D300s and perfectly fits in the front pocket of my Lowepro bag TLZ1 D300s.
Thank you to Amazon to include this article in the basket More program (just comes in a protective plastic bag, no need for more!).
