There is no need to fear, it's solid, it's powerful, it's serious. Obviously it's all manual, but if you want a remote flash to get you started in the "strobisme" without breaking the bank, should be largely your expectations.
The buttons and menus are ergonomic, it is not too lost if it is already known in advance to use a flash.
By cons, beware because there are no tips for autofocus assist light, yet very useful in low light.
