Canon Macro Twin Lite MT-24EX Flash

Canon Macro Twin Lite MT-24EX Flash Overview 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 head?s output, over a six-stop range. Features Attaches to all Canon EF macro lenses (EF 180mm f/3.5L requires Macro Lite Adapter 72C). Twin flash heads can be rotated over 80? angle around lens in 5 degree increments. Heads can be swiveled or bounced and can be removed from mounting ring for added control.
