Do-It-Yourself Macro lens

The latest The Citizen Scientist has a good how to for making a DIY macro lens for a Casio EX-Z120 – “To assemble a macro lens for your camera, you need the cap of a film container like the one shown in Fig. 1. Use a knife to cut away the center of the cap as shown in Fig. 2. Attach a biconvex lens with a diameter of about 27 mm to the cap as shown in Fig. 3. The lens should be secured with glue. The lens I used came from an old binocular. Finally, mount the lens onto the end of the camera lens as shown in the final frame adjacent to Fig. 3.” – Link.
