The Canon Macro Ring Lite MR-14EX, for close-up and macro photography, is loaded with features. 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.

The Canon MT-24EX mounting ring can be attached directly to the front of the macro lens and has a forward tilting control unit. As the control unit will not hit the flash, even when the mounting ring is rotated, the design makes the MT-24EX ideal for use with any of 5 Canon EF macro lenses. The flash heads are fitted to the rotating mounting ring and can be individually rotated both horizontally and vertically for maximum flexibility and control. As well as this it is possible to detach the flash heads from the mounting ring further expanding the range of possible lighting setups. The MT-24EX is a highly adaptable lighting system for all kinds of close-up and creative photography.
