I have just received the product and then the nasty surprise, because on the package is to read: ". If the camera's hot shoe mounted (at Sony hotshoe with optional accessories holder)" So far, so bad. So once looked quickly at Amazon for the appropriate adapter, so can not be that expensive. Is he yet unfortunately, it costs namely for example by the company BIG about 20, more than the rain gear. So does the whole unfortunately no sense.
Conclusion for all owners of Sony cameras: Stay away, unless you are already owner of a corresponding adapter.
PS: As a special gimmick is mounted on the product photo on Amazon rain protection on a Sony camera. O_o
