A very potent flash unit, very powerful (more powerful than the far more expensive Nikon SB800), with easy colorful instructions. The flash unit has a colorful diplay in which you can select your settings with the relevant buttons, as shown in the photos. The flash unit is fully functional and is indeed in excellent condition. The only drawback is the broken diffuser panel, which is rarely used in the field. This only affects the width of the flash beam when wideangle lenses are used. When this is pulled back in its normal condition, the flash head is immaculate, no scratches or dents. Comes in its original box with the original instructions for use.
