I have the old M series 100mm with a 49mm filter thread, which I see the later DFA 100mm macro has too. I use an old Cobra Macroflash (also called Centron MR20, Vivitar 5000, and Starblitz 1000-Auto Macro Lite) ring flash which cost me about £15 on Ebay and does the job. It attaches to the lens filter thread via an adaptor, which is a bit fiddly (not as easy as attaching a simple filter). I have no worries about the strength of the set-up; the working is slow, but that is not a problem for the type of macro pictures I take - mostly technical.
