Do-it-yourselfer Chris Knight explains that the innards of cheap binoculars can double as a macro lens for digital SLR cameras and camcorders and can prove especially useful in situations when a macro lens is unavailable. Unscrew the binoculars and remove the front lenses. Tape the lenses securely to the front of your camera. When you first start the camera up, it will take some time to acquire the best focus, but with practice, you'll be able to capture objects at extreme close-up detail.
