Good fit. Even if it doesn't, it includes instructions on how to get the best fit. For some reason I thought it was hard rubber, but it looks like 3D printed plastic. Not bad, I guess I just didn't do enough research beforehand. Hard rubber probably wouldn't be good for focus tracking. In any case, the mechanism fits perfectly. I use it for videos, my wife takes pictures and it doesn't bother her or bother her using it. It never leaves my lens and has made one of my favorite lenses even more useful.
