I have here for a tripod mount for my 70-200mmm 1: 4L searched and two had in the immediate selection. Ultimately, I decided due to the lower price of this copy. I have to say the surface does not look super nice because the film is adhered to the metal ring a few threw blow, but served its purpose-way free. The dispatch from Hong Kong costs aufreis only 2 and takes a bit. But who wait can get a robust and qualitätive Stativschelle. For beginners just right to photographing with a tripod.
