Who It’s For:
This is Nikon’s second best professional Speedlight, which is for anyone who needs a (comparably) light weight, powerful flash. It’s a little big on top of a camera, but it’s definitely worth the extra heft because this is a very versatile flash. It’s not as powerful as the SB-900 or SB-910, but it’s cheaper, so if you don’t need the extra features and extra power, this is a great flash for people on a budget.
What We Like:
Attachable Filters: The SB-700 has attachable filters that communicate with the camera to adjust white balance.
Moderate Zoom Range: The SB-700’s zoom range is 24-120mm
AF Assist: This is a huge benefit for those of you shooting in dark places.
Size: This flash is considerably smaller than the SB-900 or SB-910, which can be a big benefit.
Price: This flash is considerably cheaper than the SB-910.
What We Don’t:
No PC Sync: This flash doesn’t have a PC Sync port so you’ll have to buy an adapter if you want to use a pocket wizard or other radio trigger.
I love this flash. I have the SB900 as well but I always grab the SB700 first because for most shots I don't need the extra power of the SB900 and this one is much easier to use and is lighter than the SB900. I highly recommend this flash.
Its easy to change modes from dedicated to remote flash by just rotating the wheel/knob, and not having to press and hold the buttons. The diffuser loses it grip on the side notches after a while.
