Macro lenses are among the most-fun lenses available and the Canon Macro Ring Lite MR-14EX II Flash makes getting great images with these lenses very easy.
The poppy is an especially big challenge to light from a top-down orientation. There are very few good methods to get light around the end of a macro lens without creating unwanted shadows deep inside this flower. The macro ring lite, with a pair of circular flash tubes positioned at the end of the lens, wraps a light around the flower's significantly-raised pistil while avoiding shadows created by the also-significantly-raised petals.
This result is what I was looking for. The lighting is somewhat flat, but there is plenty of color and detail in the poppy to keep me satisfied. This was a very easy picture to capture with the ring lite mounted.
