Last year i made this shot of fly, its handheld close up picture with EF-S18-55mm f/3.5-5.6 IS II lens at its maximum 55mm, this is lens i get to camera(EOS1300D) which i still use. I was very lucky with this fly, because it pose for me for quite a few seconds sitting on leaf of Greek nut tree.
Edit: i forgot to mention important detail - i used cheapest extension tubes i found(but ones which transfer aperture etc.)
