Forgot to say, from time to time (for tiny subjects) I also use an inverted 28 mm. sigma lens, combined with one, two or the three extension-tubes and the flash, evidently.
Nevertheless I restrict the inverted lens to the minimum, you dont know how akward it is focusing with it in poor lighting conditions (be sure its a nightmare).
