Thanks for the info. I had never seen a O-Flash before. Just curious, but exactly why are light rings such a bad idea for insect shooting outdoors?
I am no expert but, I will share what I do know.
Unless you spend more money, ring lights are generally under powered. A decent speed light allows shorter duration flash to help freeze any movement from you or your subject. Lots of diffusion options with a speed light.
Ring lights are mounted in one position which may cause subjects to look kinda flat. Any reflections or catch light will come out as a distinct ring, such as a jumping spider's eyes. It can also be tricky to diffuse the light from a ring.
a ring light works just fine for lots of people. It is convenient for sure. It's just that the macro photographers I shoot with have already evolved so I don't have to.
I have both, a ring light and O-Flash that never see the light of day because, while the results were good with them, I wanted better so, I emulated what some of the really good macro photographers were doing....
Hopefully, some of the more accomplished/experienced Macro guys like Orion will chime in here.
