Nissin Di866 Mark II Professional Speedlite Flash Unit is the most powerful flashgun in the Nissin range.
“An all round excellent flash. Very simple to set up as either master or slave, working flawlessly with Nikon SB700 in a mixed system. Remarkable ability to be controlled by Nikon D7000 in commander mode without line of site indoors. Full TTL, Manual and HSS make this unit stand out. Cracking piece of kit and many thanks to Jonathan for taking me through the choices so patiently.” ~Customer review
