The MT-24EX mounting ring can be attached directly to the front of the macro lens & 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 to be used with any of Canon EF macro lenses. The flash heads are fitted to the rotating mounting ring & can be individually rotated both horizontally & vertically for maximum flexibility & 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 & creative photography.
