Easy! Cell Phone Camera Macro Mod (5X Zoom)
Hack N Mod offers an incredibly simple cell phone camera mod that delivers striking results. All you need is a lens from an old DVD player and you can magnify your zoom by five times.
"You'll find the lens directly under the disk tray. If you've just upgraded to Blu-Ray, now you have something to do with your old DVD player. Or, if you have an old computer with a DVD drive, that will work as well.
Literally, all you do is remove the lens from the player and place it on top of your phone's camera as shown below."
