Well caught, I have experienced great difficulty trying to capture these creatures; they move so fast! A very good photograph. How did you use the built-in flash? with my K20D I had to make a bracket to attach to the hot shoe and tilt the built-in flash down slightly.

Thanks, Colin.

I've made up a diffuser from a plastic milk carton.
Basically, cut off the bottom of the bottle, leaving a square "tube", closed at one end. About 1/2" from the closed end, cut a square hole about 2" x 2" BUT leaving a tongue protuding from the edge of the hole nearest the open end of the "tube".
These dims may need fine-tuning to your flash/camera dimensions.

The idea is to pop-up the flash, sit the diffuser over the flash, the closed end facing forward, with the tongue fitting into the hot-shoe slot. On mine, I left the tongue long enough to fold it over, which makes it a more snug fit in the hot-shoe slot.

I've found this arrangment works v.well, enabling the use of f16, iso200 @1:1 with my D FA 100mm Macro.

Good luck!

Roger.
