Yes. I ordered it because I tried to evaluate the shutter vibration with two collared Nikon lenses (70-200 and 300). The lens barrels on bothmade of plastic at the place where the original (and again expensive) genuine collar is attached. That made quite a jump (around 2mm at 4 m distance and yes, there is a difference between no mirror-up and active mirror-up).
I ordered a couple of other things at Mengs / gumptrade and thought, for little more than 30 $ (collar was around 180) I give it a try. But they have also (cheaply designed and made) macro rails with geared rails. If you're very serious about macro rail, I'd recommend Novoflex first but the Mengs junk versions work as well. Just less smooth.
