I had been anxiously waiting for the two evaluation units to arrive and finally they arrived two days ago, December 15, 2014. The small Nissin i40 is made for Canon, Nikon, Micro Four Thirds, Sony and Fuji cameras. With a current street price of $269 this is a very affordable unit.
In the box is the flash head, a stand with a metal 1/4 20 thread for mounting on a light stand or other device, a diffuser, and a quick start instruction manual. A nice belt mountable pouch for carrying the unit is provided and they include a carabiner so you can attach the pouch to any belt, strap or camera bag loops and rings. A spare set of AA batteries fits nicely in the diffuser so you can carry enough reserve power in one convenient pouch.
The i40 weighs 7 oz and fully extended is under 3 1/2 inches. The unit is powered by 4 AA batteries and unlike the larger Nissin flashes this does not have a cartridge system for the batteries. With a guide number of 40 or at ISO 100 of 131′ at 105 mm and 89′ at 35 mm position, the unit is suitable for most photographers who like to carry a handy flash for fill as well as indoor photography needs.
