My photography passion started with macro. I have the Canon mt24ex twin flash which works really well, along with a Canon 100mm and canon MP-E65 macro lenses. The stofen diffusers I used with the mt24ex are not the best...but there are many home made versions out there from a number of people, which work much better...in addition to diffusers for the 580EXii flash unit which I also have. The AK diffuser looks interesting...not sure why there is a light inside, unless it makes it easier to see the subject, as the diffuser could totally cover the subject due to its overall size. It also looks a bit cumbersome, but I'd be interested to see some real-world sample photos taken using this diffuser. It certainly would present an issue using the MP-E65, as the lens needs to be very close to the subject and this diffuser would not be practical here.
