Unbeatable price, but the original is better

But: The screw is mediocre, you get the feeling, always a bit of material to pull away.
Unfortunately, I can function to turn the lens in the clip, not really use, because the first scratches are starting lens :(
I subsequently defused all corners with the Dremel, which made it better.

The color is a little darker than my 70-200 1: 4L USM.

Shipping ran perfectly for me. Sure it takes a little longer, but when it comes Postbrief at customs without charges over.

Overall, a good solution as a permanent off-clamp. Frequent on and but would decrease clamp and lens damage.
