With large lens barrels, dSLR optics look professional and intimidating. This is why it can be difficult to take candid street shots with them. But Photojojo has a solution--the Super-Secret Spy Lens.
This attachment fits onto most lenses via adapters, and the opening along the side shows a precision mirror that reflects light into the optics. The swivel barrel lets shutterbugs take discreet shots in any direction without having to point the lens at the subject.
Photojojo's Web site lists the price for the Super-Secret Spy Lens from $50 to $85, depending on which combination of adapters you require.
