Phoenix SmartFlash RF-46N TTL Macro Ringlight for Nikon iTTL

The Phoenix RF-46N Macro TTL Ringlight provides full TTL control (including i-TTL) with both digital and film SLR cameras. This allows for accurate exposures of close-up subjects. When shooting at extremely short distances, relatively minor movement of lighting and subject results in relatively large changes of exposure. TTL metering eliminates the need for lengthy calculations of exposure, because the inherent loss of light at macro distances can automatically be accounted for with ease.
