As specified in the technical data the inner diameter is 47,5mm. There is no thread inside, the thread is just like a baffle against straylight.. There is no need to attach filters in this place because its part of the UFC system and the fitlers are placed in UFC filter holders

Please click on one of the filter sizes and scroll down to "technical specifications". When you click on that, you will find the size and thickness of the filter. The bandwith is shown in a graphic on the top left of the page, in the image gallery
