The pictures:Lensadapter1,Lensadapter2,Lensadapter3, and Lensadapter4, are of lens adapters and lenses for
a Sony Cybershot DSC-W120. 
   Lensadapter1 shows an achromat lens that I cut out of a larger lens along with the annulus left over, the chuck, and the cutter. The lens was held in the chuck with dopping wax, the type of wax used for holding stones when grinding them. The chuck is bored to a slip fit for the lens in order to hold the lens concentric. 
   Lensadapter2 shows the adapter that fits on the camera, the thumb screw that holds the adapter to the camera, and two lens adapter rings. The camera adapter is threaded m37x.75. The camera adapter is also threaded 1/4-20 so that a tripod can be used while the adapter is attached to the camera.
   Lensadapter3 shows a ring adapter screwed in the camera adapter and a close up lens screwed into the ring adapter.
   Lensadapter4 shows a 1.5 tele/.5 wide angle lens combo screwed into the camera adapter and another view of a close up lens screwed into a ring adapter.
