The original Stativschelle Nikon is priced at 120 euros upwards hopeless. No wonder you look around for alternatives and a very good alternative for the RT-1 tripod clamp suitable for the AF-S I have found 70-200 / 4 VR. The product offered here "suits, sitting, wobbles and has air". So seriously: Mounted on the lens, of course, nothing wobbles and I have absolutely no complaints about the processing and material properties. Normally I'm not a fan of "Made in China" copies, but in this case you have to the insolent price for Nikon-original actually already boycott on principle.
