This replacement foot is so great - solid fit, bigger than the original, and includes a QD attachment point, which was important for me. I especially love how the knob works that unlocks the rotation of the lens - you actually have to turn it quite a bit to get it to move, which means it's very finely adjustable to get just the right amount of grip or tightness on the lens. It also means when you go the other way to tighten it, it's very tight. Love it!
