I love macro. The world is so vast when you have a macro lens. With a normal lens I open my door and look at my yard, bleh...boring.
But with a macro lens (or extension tubes) my little 3/4 acre grows to Amazon proportions! You can always find something interesting to shoot when your frames are 2cm wide.
First image is Physalis pruinosa or Ground Cherry blossom.
Second is a 2mm Anthrenus verbasci or Carpet Beetle sipping nectar from a tiny Dill flower.
Third is Sisyrinchium or Blue-eyed Grass.
