Giant Swallowtail -------

Summer seems to be in its zenith and I try to catch the essence of this season in light and colors. The good old Sigma 150, f/2.8 macro lens is still a perfect tool for this kind of shooting. To get the best out of it I shoot wide open most of the time, rendering the background with a nice bokeh. Focus has to be on the spot (eye and body) due to the shallow depth of field at f/2.8 or f/3.2. The butterflies have never a quiet moment and continuous-servo autofocus is the only way to get a sharp image.
