I have a Cokin filter on my dvx100. From what I can tell the 100 and 100A have the same 72 mm threads. You would have to buy an adapter for the Colkin P frame. The P is bigger than the A. The P is around 3+. All in all I have about 175.00 in adaptor, frame, and some cheap jell. Remember... the camera adds and subtracts color. For example blue and yellow does not mean green. There have been some threads on this subject. I personaly use the presets and memorise the offset.
Good luck!
