This 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.

This attachable supplementary flash can be used to capture photographic subjects that are too distant for the built-in flash to illuminate. The range of the flash is approximately twice the range of the camera's built-in flash. This figure will vary according to such factors as the camera lens brightness (f/number), the zoom setting and the ISO speed setting.

Designed for automatic operation only, the 220EX flash unit excels at providing natural-looking balanced flash exposures. When attached to the advanced cameras, such as EOS IX, EOS Elan II/Elan IIe, or EOS Rebel G, the 220EX delivers the benefits of the Canon's superior technology. These include Canon's unique E-TTL evaluative pre-stored flash exposure control system, FE Lock for a new dimension of creative control and FP Flash (high-speed sync) for flash photography up to maximum shutter speed. When used with other cameras, it operates as a TTL autoflash (off-the-film flash metering).When in E-TTL operation, flash exposure is measured and controlled by the camera in combination with Canon's AIM system. Subject position, ambient light level, evaluative metering and pre-flash data are instantly analyzed, including heavy backlighting or reflections from background windows or mirrors.

Most impressively, 420EX' wireless E-TTL compatibility permits it to function as a "slave" unit, triggered by a 550EX; ST-E2, or MR-14EX. Any number of 420EX and 550EX Speedlites can be combined as "slave" units.
