Meant to fit the end of your SLR’s zoom lens, this guy has a secret cut-out on the side and a precision mirror assembly inside. In short, you can shoot left, right, up, or down (it swivels 360 degrees), all while appearing to shoot straight ahead.
You better watch the video to know how to use this cool thing…You can be the real Secret Agent with this!!! :)
