hi,this Pro Kit filter can not used on 95mm size lens,because we do not have 95mm adapter ring. 

Hello! If you use the magnetic UV filter separately, or use the magnetic adapter ring together with the CPL filter, you can use a normal lens hood on it. Does not require a larger thread. If you use the magnetic adapter ring together with the ND1000 filter, you cannot use another lens hood on it. 

It’s a standard 1/4"-20 Female to 3/8"-16 Male Screw Adapter Reducer Bushing Converter. This unit comes with one in the box, but fair warning. It tends to stick on the original 3/8” tripod head. I’d suggest possible gluing the nut in the unit or at least waxing the original head before use. 

hello , if you put a lens hood on 52mm filter, you need a 55mm lens hood 

The kit comes with 9 adapter rings for all sorts of lens sizes. You screw the adapter onto your lens, then the square piece screws onto the adapter and the filters slide into the square piece. The lens sizes the adapters fit are 49 mm, 52 mm, 55 mm, 58 mm, 62 mm, 67 mm, 72 mm, 77 mm and 82 mm. It matters more of the lens size than the camera you are using. Have fun with them!!
