For several weeks, as soon as we turned our garden fountain on, the wasps arrived to drink from the damp patches. I set up the 7D with 150mm Sigma EX Macro and Sigma rig flash on my old Benbo tripod and gave chase. I also added the Sigma EX 2X converter - something I only do if I want a really big image - this will be 2:1. The Sigma converter is the best I have ever seen - it is very difficult to see any quality loss - possibly because the 150mm is such a superb lens.
Manual focus and camera settings. 1/200 @ f18. Flash on auto, but with +2 stops exposure compensation set from experience.
