Candid shots of people just living their lives and doing real things completely unaware that they were on camera. The Super-Secret Spy Lens($50), which is basically a periscope that attaches your SLR's zoom lens, allows your point that zoom lens as a "fake out" object. It uses a secret cut-out on the side and a precision mirror assembly inside to let you point the real subjects. It swivels 360 degrees, you can shoot left, right, up, or down, all while appearing to shoot straight ahead.
