What will your camera be attached to?

If you own a Nikonos Camera or a Sea and Sea Motor Marine II you need to decide whether you will use the tray you own or get one of Ultralight’s trays.
See trays below. Trays for Digital cameras available, see digital still housing section.

For all trays you will need to start building your arm set with a Base Adapter.

For a Nikonos tray you have the choice of a handle (AC-H), a quick disconnect handle (AC-HQD) or a base ball adapter (AD-3816). Any of these three
choices slide into the slot on the Nikonos tray. If you are only using one strobe then the base fits on the left side of the tray. All handles have a ball on the
top of them. The handles and the AD-3816 are base adapters.

If you own a Sea and Sea tray our handles will not fit on it. Your tray may have a “T” plate on it, so you would start your arm system off with a BA-TG
which fits over this “T” plate. If you do not have a “T” plate on your tray then you can put any number of base adapters on this tray

"T" plate,
BA-TP with BA-TG
  • BA-TP - A “T” plate
  • BA-AQW - Fixed ball screws directly onto the handle
  • BA-DB - a dovetail shoe into which you would slide a BA-DT (straight dovetail)
  • BA-DB - a dovetail shoe into which you would slide a BA-AD (angled dovetail)
The BA-TP will then require a BA-TG to go over it. The BA-DB will require a BA-AD or a BA-DT to slide into it. It is
important to inform your dealer what tray you are using so they can supply the appropriate thread size bolt or screw for
the base adapter. Some are metric, others are US threads.

three trays for you.

  • TR-NKS - A single tray, designed for use with only strobe
  • TR-NKD - A double tray, designed for use with one or two strobes

On the single or double tray you can put a handle
(
AC-H) or a quick disconnect handle (AC-HQD) on the
left. You can put a
AD-3816 on the right side for your
second strobe or on both side instead of a handle for
attaching your strobes. These handles and
AD-3816
are base adapters

If you are using dual strobes with your pivot tray, you will need a base adapter for the right arm set. You have three choices:
  • BA-AD - Dovetail shoe (plate) with a BA-AD, an angled dovetail ball
  • BA-DB - Dovetail shoe (plate) with a BA-DT, dovetail ball
  • BA-AQN - A fixed base ball direct to the pivot

If you do not desire a handle on the left, these three base adapters can be used on the left side also.
