Amphibico HousingsAmphibicio Housings - Phenom or Invader, Part name: BA-HSS7

  • Most of the Amphibico housings have a “T” plate attached to the middle of the housing or on each handle. The base adapter that fits on this “T” plate is the BA-TG. The Amphibico Explorer MVI housing for the Canon Optura Camcorder has a “cold shoe” on the top. Our AD-HS, adapter will fit into this cold shoe. Another way to mount your lights to this housing is to use a tray TR-SBLD, and add one or two handles at the ends to have a base for starting your arm.AD-3816

No Responses to “Ultralight”

  1. Hi,
    Today I have seen your transformation of a Patima housing.
    I’m owner of an old Patima and I would like to be able to make your transformation.
    My Patima is not my main housing but I want to give it a second life.
    Any aspect to highlight or simply follow the instructions of your blog?
    thank you very much
