Information

The ringflash fits all Acute flash generators and is an entirely moblile source of light. The adjustable tripod mount bracket and wide interior (100mm diameter) allows for fitting all types of cameras and lenses in many formats.

Optional PR Softlight Reflector increases the size of the light source, with fewer sharp shadows. Optional PR Close-Up Reflector focuses the light source 20" (50 cm) in front of the camera lens. With smaller objects, the effect is completely shadow free.

Maximum firing rate is 9600 w/s per minute, equal to 4 flashes per minute at 2400 w/s, 8 flashes at 1200, 16 at 600, 32 at 300, or 64 flashes per minute at 150 w/s.
