Always wanted to take super close up photo's of bugs and small stuff? This is an quick, easy and cheap way to get some nice results for very little effort and money, and still keep all the camera settings like aperature.
You will need:
one slr lens to dismantle, mine was one that had a broken focusing mechanism, but you can get the same part needed from nearly any lens, get cheap one from a second hand sale/flea market for peanuts
blu-tac, to fix the macrogyver onto the front of your normal lens.
set of mini screwdrivers to dismantle the lens.
Step 1: Step 1
With your bits assembled, the first step is to dismantle the surplus lens. most of the time the screws are hidden under the rubber focusing ring, use a screwdriver to slip it off. there may or may not be other screws on the mount part of the lens depending on what lens you have.
Step 2: Step 2
once you have unscrewed all the micro screws, it "should" just be a matter of gently twisting the lens barrel, almost as if you were focusing it, until it comes apart. all the internal parts of the lens i used came out of the lens assembly by turning them or pulling gently in the correct way, with one micro screw holding a part in place.
the element you'll need is the rear one, this may be different with other lenses so just try each element by holding it manually in front of your camera and checking.
it will basically look like it has a small lens on the front with a larger lens on the rear.
Step 3: Step 3
When you have identified the right element, roll out some blu-tac into thin bits and carefully position around the edge of the wider part of the lens element housing, and then carefully position onto the front of the lens you will be using, make sure it's sticking to the lens casing, and not the front of the lens itself as it will be a pain to clean when you're not using it.
Make sure its level and not crooked.
