Nikon SU-800 Flash Commander, CLS
This is the heart and soul of Nikon’s CLS (Creative Lighting System). It is the master and commander of both, the SB-600 and the SB-800. The possibilities with this little device are endless as it can be used in flash groups of 1,2,3, and A,B,C for a lot of lighting situations as well as creativity. The SB-800 can be used as a commander, but in some cases it can leave unwanted residual light. As per my tests, the SU-800 almost doubles the commander distance range compared to the 800 flash unit. Another plus is that the SU-800 menu is much more straightforward than that on SB-800. This is one of the best accessories I purchased in a long time with an approximate price tag of $249.
