The advantage of the Sprayoff micro and mini can be shortlisted as follows:
Both fit within its specific matte box, taking only the space of the front filter holder.
Both are lightweight (Sprayoff micro: 500 gr., Sprayoff mini: 980 gr.)
Both can be powered out of the camera with 24V if available, since the power consumption is not higher than for a regularly used onboard monitor (Sprayoff micro: 0,3 amps., Sprayoff mini: 0,8 amps.)
Easy and very fast setup by sliding in and “plug’n play”.
Large optical width to cover even wide-angle lenses following disc diameters: Sprayoff micro: 118mm, Sprayoff mini: 169 mm
