This lens recycle from disposable camera and transform it to a body cap lens.It could be one of the best weapon for street photography. The Fixed aperture and focus free makes sure you can capture the moments you want. The lens does not have and does not need to focus, the aperture is f/10, the depth of field is basically 1.6 meters away to infinity. A powerful tool for street shooting. And it's small and non-invasive. Just press the shutter when the camera is hanging on the chest or shaking hands. They are all remanufactured by hand and may have some small flaws (the lens may not rule out some small gray scratches, etc.), But each lens has been checked and adjusted, and the flaws will not affect the imaging and use.
