The great thing about this project is that you can make it as long/short as you yourself require (longer tube=closer macro) AND it will fit with any lens made for the canon EOS series! :)
one thing to note, if you make a long tube it will allow you to take photos SUPERCLOSE, but your "focus-range" will be minimal, meaning that if the object your taking a picture of has any curves, only a tiny portion will be in focus
Things you will need!!
Cover for your DSLR Body
Cover for your DSLR lens, as in socketcover.
A tube of some sort, I used a roll that used to have giftrope on it (anything that dosent let through light can work)
A hot glue gun
A dremel or other tool for making holes in your covers
a bottle or other tube to fit over the "lens-extension" to make it prettier :)
Step 1: CUTTING! WOO!!
These caps will be Glued onto the ends of the tube, allowing the tube to fit into your DSLR body like a lens would.
Then the same goes for the other end of the tube, but with the socketcap that allows you to put your lens into the extension.
