Hi, I have been trying for quite some time to shoot flowers / bees with my 30D + 100mm macro + flash. I am not satisfied about the focussing or DOF of the objects as it appears partly blurred and partly focussed depending on the area focussed. Very small area focussed makeing the viewing unimpressive. Am I missing the anything? I have seen many macro shots on the web with crystal clear sharpness of most of the subject and with the gear I use. Does this need only practice or editing or some equipment like extension tubes etc? I am bit frustrated on this... and request guidence.
