I had ordered this clip due to the rather positive reviews on Amazon. The clamp fits color not quite to the lens, the resist pattern is different, but does not bother me. But what disappointed me: in the area of the joint must be using a file deburr the material, otherwise the lens is scratched! I had the fixing fortunately initially not entirely tightened and the clamp until removed again, there was already an impression in the paint, but I was able to rub again. So then filing down and a round stuck scotch tape on the lens for protection. Both the tripod thread and the thread in which engages the locking screw are only superficially cut the grooves have little depth. I expect that the material is here soon worn out and the screws by turn. If you screw the locking screw without a lens, then the gap a few millimeters further includes, and already since the screw rotates through. So there is very little material. The locking screw wobbles, so the set screw sits slightly askew. The set screw is not well fixed in the screw, while trying to open the clamp, I had the set screw in his hand, the threaded pin remained in the clamp so that it could be opened only times not. Botch! Since I rarely make shots from the tripod, I keep the part now, but put no hopes in the capacity. I would not buy this product again.
