Flash photography is a complicated subject. As soon as you experiment with flash (and most likely that will be the incorporated unit in your phone or digital camera), you learn that pictures taken with flash are bad. That is true for DIRECT flash in low light conditions, however direct flash can also (and is absolutely necessary to) get wonderful results as fill flash, in contrasty lighting situations.
Enter big bulky flash guns with big displays and a lot of buttons, that you see on paparazzi’s cameras at the end of the red carpet. These look like you need a doctorate and another pair of hands to operate them.
That is definitely not the case with Nissin Di700, a $260 brilliant unit that is meant to do everything you need from a powerful flash gun, right out of the box, even if you have never held a flash gun in your life. And it achieves that objective with flying colours.
This review is based on a Nikon version which i have used as my main flash gun for more than a year, but the Di700 is also available for Canon and Sony DSLRs.
