Strobist@blogspot got their hands on the new middle-class Nikon flashgun : the SB-700. The SB-700 designed to become the succesor of Nikon SB-600 with slightly less power ( GN28, ISO 100) , zoom covers wide 24-120mm angle of view, and advanced functionality of the SB-900 Speedlight.
Review highlights :
the SB-700 is a very well-built and capable flash
this is truly the Nikon SB-900′s little brother. The design and interface are pretty much exact replicas
The optical port is mounted flush, rather than recessed
The button sequence for getting an SB-700 into SU-4 slave mode is just like the SB-900
The head goes 180 degrees both ways, so you will not need to do the chicken neck mod
The SB-700s have awesome build quality, super-fast recycle and lots of bells and whistles. But are they worth 2X an LP160? That is totally a case-by-case call, depending on your wallet and how much you will use them.
