Biggest problem I have with this rig is that illuminates a ring of light, with the center of the images substantially darker. More so the closer the subject is to the lens. I've had several ring-lights, Pentax, and they are designed to light a fairly near frame evenly. I had trouble in Costa Rica photographing insects and frogs at night with the ring-light. Little modeling of the subjects as the light was too even. Ended up using two small flashes on flexible arms, which allowed me to control the direction light came from, and differentiate between Main & Fill. Downside to that was having to use my headlamp for focusing as well as finding subjects in the first place. Most ring-lights have modeling lights built in. After I got home, I re-rigged the flash on arms to be triggered by the flash of the ring-light using one of those little triggering sensors (can't think of the name - duh) which gave me the best of both worlds. Never got back to CR, or anywhere else tropical, unless you count Cabo. It's better for sunrises and sunsets, no flash needed.
