This is to get the really small things on camera. It works for almost any digital camera and I found it works really well for mine.

Step 1: So...

You will need:

An x-acto knife or a verrrrrry sharp rock. An x-acto knife works best though. (Not shown)
A piece of cardboard
A convex lens. (I got mine from an old microscope)

What is the difference between convex and concave you ask? Concave goes in and convex goes out. The one I use went out on both sides.

Step 2: Cut!

Trace around the lens on the cardboard with an x-acto knife or sharp rock. Cut out the circle.

Step 3: Easy As 1,2,3!

Now put the lens into the hole in the cardboard, and make sure it stays in. If it doesn't stay in the hole you may need to use some glue to hold it in.

Step 4: Done

Ok so you're done. To use this you can just hold it really close to the camera lens, not touching it, and take a picture. However, this is for reallllllly close up pictures, so you probably wouldn't use it to make an instructable. You would need a different lens, one that didn't magnify everything so much.

Here are some pro's and con's of this thingamajig.
Pros:

Small, compact, can fit in pocket or wallet
Inexpensive
Easy to make

Cons:

You need to be careful you dont hit the camera lens with it.
You need to hold it on (It can be changed so that you don't have to hold it on though)
(This one anyway) You have to be really close up to whatever you're taking a picture of.
