Thanks guys; I've been using this lens for a year and have been perfecting my technique during that time. It's really difficult working at such high magnification as the Depth of Field is very small, even at an aperture of F14. My new Canon Macro ring flash really makes a difference
Here is my macro setup.
Canon 20D + BG-E2 Grip
Canon 100mm Macro lens
Kenko Extension tubes (12, 20 & 36)
Canon MR-14 Macro Ring Flash
