SB-700 is an upgrade to the older SB-600 with refined design in both electronics and mechanics. It is a more reliable and durable flash in many ways than the SB-600 except the weakly made plastic foot section. Professionals consider the unit as more like a compact version of SB-9XX line supporting both master and slave functions. It features a newly designed interior zoom head and locking shoe section which is identical to SB-900 and SB-910 models. SB-700 shares similar features and menu system of SB-900 and SB-910 as well. The SB-700 is part of Nikon's Creative Lighting System (CLS) and features the intelligent-TTL (i-TTL) exposure mode. It weighs approximately 360 g without 4 AA batteries. It is mostly made in China. Announced September 2010 and available since October 2010.
