Some quick macros shot last night with a inverted free-lensing technique (a 50mm unattached and inverted in front of the camera). Basically, your camera shoots without a lens on it and you focus manually by moving the camera and lens towards or away from the subject.
Testing out my new lens, the Canon 70-200mm. You can appreciate the awesome sharpness and the lovely bokeh here. The "sun" is a light from the building in front of mine, had to compose it to be a better "test" picture :).
