After spotting a thread in which Jonmurgie used extension tubes for macro shots:
I figured I should have some for myself, as I couldn't afford a true macro lens. So I went on DealExtreme and bought their generic Canon extension tubes for $9 shipped. They arrived today, so I immediately started experimenting. These are the first few pics I shot - take into account that these are not showcase pictures, they were taken under the nasty light from my desklamp with the camera handheld just to test if these were as good as I hoped:
Shturmanskie vintage dial
Wittnauer watch movement
Asian 6497 regulator
Yeah baby. And I'm not even trying yet.
These are going to be my favourite toys for the next few days. Incredibly hard to use, but I imagine that it'll go much easier when I put the cam on a tripod and have a proper lighting setup rigged.
