Have my macro lens Canon EF 100mm 2.8 L IS USM macro lens (67mm filter thread, image stabilized) fetched. For macro photography you need a little more light, since I came to the ring flash from Dorr, the Zeiss I would have liked better but much more expensive. After the first test, I was still excited, dissolves quickly even with series recordings, only the connecting cable is fixed and can not be put an extra (for better installation). When photographing the cable does not bother. 5 stars because the functionality has convinced me.
