Macro Twin Lite MT-24EX works different to traditional ring-lites which offer a more directional light source with its changeable flash heads. The units can even be mounted off and placed off-camera to offer a creative light setup. The guide number is 78/22m at ISO 100.
The new Macro Twin Lite gives serious close-up, nature, and macro enthusiasts a different option in macro lighting - a directional quality of light, as opposed to the rather "Flat" character of the traditional ring lite. Two separate flash heads can be swiveled around the lens, can be aimed separately, and even removed from their holder and mounted off-camera. Like the MR-14EX, the new Macro Twin Lite MT-24EX is fully E-TTL compatible with all EOS bodies, including digital SLRs, and even allows Wireless E-TTL flash control with one or more 550EX and/or 420EX "slave units". It also provides easy ratio control of each flash heads output, over a six-stop range.
