I am working on a little experiment where I am trying to connect a step up ring to part of one of those cheap Nikon extension tubes. The threads on it fall between 55mm and 58mm, and I feel like it is 57mm. I know this is an odd thread size, but from what I can find on ebay, it does exist. Anyway I am looking for any standard thread to 57mm step up ring. Does anyone have one or know of where I can get one? Thanks.
