As already exist some reviews, I consider myself short. The device is about twice as strong as the most integrated lightning, so that one thus gets on well with the vast majority of indoor shots. The biggest advantage as opposed to integrated flash is the ability to swing the reflector toward the ceiling, so leave the light on the subject indirectly via the ceiling. This overexposure z. B. of faces is avoided even at close range and in portraiture, producing images with gorgeous natural color mood. The device is very easy to use via z. B. the D 40 also fully manual. The flash is surprisingly lightweight and small in relation to its performance. The workmanship is typical niko outstanding. So all in all highly recommended, one should a be clear who would illuminate gym large spaces, must resort to the next larger models, all others can buy without hesitation.
