Recycling Project - A Broken Glass To A Fisheye Lens
UPDATE: Pat Joyce jest released a complete set of instructions for this mod.
It happened to all of us. At one point or another our beloved glass falls on the floor and dies. (Yes, by glass I mean lens - we're trying some hard photo talk here on DIYP).
If you had a UV or Haze filter on the lens glass, you may have protected it from any minor damage. If you tried some camera tossing and missed, you'd better collect your insurance money. Or waitaminute. As Miracle Max would say the lens may only be mostly dead.
All you need is a broken Sigma glass and a tube. An instant fish eye lens for your point and shoot.
Hey it even does timelapse:
or goes for a handheld bicycle ride. (Yes, it can be mounted on the steering)
