Live hacker has a video showing you how to turn a standard camera lens into a Macro Lens using the glass out of a pair of Binoculars. Very cool stuff. nice results!
Using only some sticky tape and an old pair of glasses, this tutorial over Photojojo shows you how to build a FishEye lens for your SLR and DSLR. Very cool stuff. Now looking into doing this. i have seen some very nice shots with Fish Eye lenses. A Friend of mine in work took some shots at the WRC event in Sligo, and there are some amazing photos.
