*Updated Dec. 9, 2009.*
I had some lenses from various sources sitting around and wanted to devise an easy way to use them with my camera phone to take magnified pictures and videos. At first, I just had small metal bezels that I used to hold the lenses up to the camera lens. This was clumsy and upon getting the camera close enough to focus, all of the light was crowded out. These are the problems I intended to solve with this device. This is what I came up with.
Mine is built specifically for the iPhone. However, you can adjust the design to fit the phone you have. I am aware of the magnification apps for the iPhone that use digital magnification. They do not achieve the same magnigication strength and clarity as optical magnification.
