Here is some information about the Rycote InVision Microphone Shock Mount:

This is the Hot Shoe version- INV-Video 042901.  What I haven’t found mention is that in addition to having the hot shoe mount, it also features 1/4″ female threading and 3/8″ male stud.  I’m using it with an Oktava MK-012-01 mic and it works well.
