The impression was of two minds: the optical quality of the viewfinder gets safely five star, he is now an alternative. The version of the optics seem to be of the cheapest plastic, which also needs to be a disadvantage, but the walk to the hot shoe is just bad. He is the standard hotshoe much too stiff, so that has to be worked during connection and disconnection with great force. This acknowledged the version with unpleasant noises that have moved me to immediate return. Thus, the envelope gets at best two star. A viewfinder is an additional component to the camera as needed up. To this end, it is my opinion requires that not only the look but also the handling right. Since this is not the case, remain only three stars.
If you can live with it, but the bottom line is a visually very good product that does the job. Whether it is also durable, I can not say more because I have but decided in the end for the original.
