There are two common versions - one is roughly f/1.5 and the other about f/1.2, and they also have differing diameters. As this also results in different focal lengths, there needs to be a couple of changes to support both versions. Further, the design is flexible enough that almost any lightweight lens can be used with some modifications to the dimensions. Materials Black Gaffa Tape. Not duct tape, gaffa. It makes a difference.
