This is a single 67mm lens side adapter for KANI HT3 HT2/ 100mm holder. When shooting with multiple lenses, you can quickly change the holder without having to replace the adapter every time. Works with either HT3/HT2 type.
67mm filter diameter on lens side Fits directly on lenses with a 67mm filter diameter, but for other lenses use a variety of step-up rings sold separately.
There are no screws on the outer side of the screw, so you cannot install a filter or lens cap. Please use the special adapter ring cap C100 for the cap.
