Canon Macro Ring Lite MR-14EX review
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.
