need MACRO lens!!!

I’ve decided that i need a macro lens… but i can’t afford one… so i decided i need a Achromatic lens… can’t also afford this. BUT! Today i spoke to a friend and he told me he has a macro extension tube, used but in good condition. Next week i will try some test shots, hopefully the tube is worth 50 €. So, some pictures will come soon, but for this time, here some boring macro shots… 🙂
