As for the service, shows once again that two wise thoughtful rotary switch with a clear structure are quite capable to replace a LCD display with a thousand little buttons and pointless nested menus par.
You immediately everything you need, can work very well and quickly manually or rely on automatic. Nothing is missing, absolutely nothing. Also, it has managed to create even accommodate four AA batteries in this small housing Nissin. In the wireless mode, the device can of course also be used yet. A rotary switch on, adjust channel and you can control it with another Nissin flash or Nikon. As a master, he can not be operated, but this does not bother here.
If you let it all happen so Revue, which is to make this machine capable one would now think that would be for 130 euros long enough, but I was wrong ...
A video light has this lightning namely still and that's not bad at all, even on the dial and also to use dimmable from and good when it is illuminated in the direction that you need.
The recycling times with batteries are very good, the flash is low and the range for the size more than adequate. Of course he does not replace a SB 900 or 910, but you get here for 130 euros a bit small and very fine commanded that quite mastered the everyday tasks of flashing and illuminating masterfully.
The i40 is despite its small size, a full flash that much has more than it costs, and is a clear recommendation worth it. A product that once again a positive surprise. For all owner Niko smaller DSLR s highly recommended, as well as to full-frame cars to use well, if you take do not want to carry so much.
Update March 2015
All Fuji photographer:
Also at Fuji this device is a lot better than the original of Fuji, the parameters remain the same yes. After six months use I can say that I have not changed my mind, but you should make sure from time to time to check on the charge status of its battery, because if they do not have sufficient capacity, then the flash recycling time is extended considerably or . produces the flash properly exposed pictures no more.
