Canon Speedlite Macro Ring Lite Ring-type (macro) flash

This new Ring Lite for close-up and macro shooting is loaded with features and capabilities. Now with Canon's E-TTL, it takes full advantage of the flash performance of the EOS-1v, EOS-3, and other E-TTL cameras. Circular twin flash tubes can fire at even power, or varied between them over a six-stop range, and one or more 550EX Speedlites can be used as wireless slaves along with the MR-14EX. The controller unit now has an illuminated full-info LCD panel and it accepts optional hi-capacity battery packs. Macro Ring Lite MR-14EX attaches directly to EF 50mm f/2.5 Compact Macro, EF 100mm f/2.8 Macro (both versions), and MP-E 65mm Macrophoto Lenses (can also be used with EF 180mm f/3.5L Macro USM via Macrolite Adapter 72C).
