I was excited at first by the intuitive arrangement of buttons, and the new screen & menu system of the SB-700, which promised a vast interface improvement over my trusty SB-600. However, in practice, I found myself frustrated with my new flash. My biggest 3 complaints are: 1) The battery compartment did not properly tighten itself, forcing me to press in on it when I turned the power on for the unit to actually power about half the times I went to turn it on. Minor defect in my unit? Maybe. 2) The power button itself. While the idea of a switch between Off>On>Remote On>Master On is great, the switch itself is thin/small and difficult for my big fingers to use. To get to Remote or Master, a button in the middle of the switch must be pressed, which was tricky at best, annoyingly difficult at worst. Major turn off in my mind. 3) The rotating dial with OK button in the middle for selecting things was, again, a good idea. However, I found it's operation tricky and difficult to control, and button pushes were difficult to consistently make. Controls aside, the menu selections, options, etc. were all quite intuitive and easy to understand. It was the difficulty in executing the options which frustrated me, and led me to return the unit and stick with my SB-600's.
