Camera Mounts and Accessories

Rather than come up with a prescriptive list of tripods, we should give a short guide in making a proper selection based on our minimum requirements.

Requirements:

  • 3/8" male thread size (for supports of Manfrotto 131DD double-head bar)
  • Capable of holding 2 cameras simultaneously (weight varies depending on selection of camera models).
  • Reasonably compact (~20") to fit into briefcase

Since the Manfrotto 131DD is the mounting bar we are using for the cameras, this restricts the choice of tripods to those with 3/8" threads.

  • Tripods with heads are typically 1/4" (which are not compatible with the 131DD), but there are a few with 3/8". Careful research must be taken to find these tripods.
  • Tripod legs (without heads) are typically 3/8" which is compatible with the 131DD. However using just the legs without a head may be inconvenient to use for tilt/pan adjustments.

Tripod Heads with 3/8" threads

  • Manfrotto 486 / 488 Ball Head
  • Manfrotto 468MGRC4 / 468MG

*Notes:

  • the above tripod heads have a 3/8" male thread at top to mount the Manfrotto 131DD.
  • the above tripod heads have 3/8" female tripod mount at base. Therefore selection of tripod legs needs to have a male 3/8" head mount.

Tripod Legs

  • Induro A013 Alloy (20.2" folded, 5.5 lb. load, weight 2.7 lb.)
  • Induro A014 Alloy (18" folded, 5.5 lb. load, weight 2.4 lb.)
  • Manfrotto 190XDB (21.1" folded, 11 lb. load, weight 3.5 lb.)

*Note the above tripod legs have 3/8" tripod head mount thread size.
