This should basically work with any camera that has an integrated flash. How it works: The HF-DC2 fires from any flashed scene that it "looks at" with its sensor. The unit is very easy to use; just point it in the direction you want an additional flash and take your picture with flash. So it is a slave flash and cannot be used as the only flash. It works with any camera that uses a flash, including the guy next to you who is taking pictures during set-up! You can also combine several units. In portrait photography it is sometimes useful to put a slave flash directly behind the subject.

The screws of the intermediate piece have another internal thread underneath so that they can be screwed into the camera at the top and the tripod can also be screwed in at the bottom. The flash is placed on the side of the camera.
