Gadgets: Spy Lens
I think this a real interesting gadget. I would not use it for spying per say but for candid shots of people in crowds, to get that real authentic non scripted picture. They wouldn’t have a clue you were taking their picture but at least you would get that real look.
“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.”
