This is an follow-up to an earlier post about yanking the lens from an old DVD player and using it with a cameraphone to take close-up photos.
It just so happens I have a need for a macro lens for something other than snapping picts of coins and PCB’s. I’m working on a project that involves QR codes and thought this might help me out when dealing with fixed focus cameraphones. Alas, the focal length of DVD optics are meant for things measured in millimeters, so it isn’t going to work for barcode scanning. Fortunately, after doing a little digging around, I found this handy Instructables project that uses the lens from a viewfinder of a disposable camera, a cheap rubber case, and a paper fastener, that seems like a viable solution.
