Introducing the F55 Underwater Housing
Congratulations on owning a new Gates product: the F55 housing. You’ve selected an
underwater imaging tool that will provide years of value and reliable service. We
designed the F55 specifically for the Sony F5 and F55 digital cinema cameras.
Please read through this entire guide to learn about the F55 so you can get the most out
of this imaging tool. In this section, we’ll introduce you to the features of the F55 so you
can get started.
Features
F55 has several key features:
 Lens flexibility. The F55 can accommodate a variety of different PL mount and
Nikon DSLR lenses with no change to control locations. Focus, Iris, Zoom remain
in the same location regardless of optics used.
 Full camera control. All practical controls are accessed directly with the F55
housing, as is the full menu system of the camera.
 Cinema-grade design. Lens choice and control access are just two of the many
features designed into the F55. A/R coated glass optics, optional HD-SDI surface
feed, and Seal Check are a few of the items any professional will appreciate.
Warranty Disclaimer
The F55 underwater housing is a tool that, like any tool, requires knowledge and
understanding to be effective.
Your responsibility is to learn the proper setup, use and care of the F55. Because we
can only provide you with the information necessary to do so, Gates does not warrant
the contents of your housing (e.g. your camera and lenses) under any circumstance.
We warrant the F55 as an image acquisition tool for a period of 2 years. The Seal
Check unit is warranted for 1 year. Optics (Dome and Flat ports) are warranted for a
period of 1 year or 100 hours salt water contact, whichever comes first.
Gates does not warrant optical performance or image quality.
If you have any questions about the setup, use and care of the F55, contact Gates
directly. Details are in section 5.

Lens Mount Adapters
If you are using a Sony FZ mount lens then no mount adapter is required. Continue to
the next section.
A mount adapter is required to use PL and Nikon DSLR lenses.
 FZ to PL Mount Adapter. To use PL mount lenses, install the Sony FZ to PL
adapter.
 FZ to Nikon Mount Adapter. Nikon DSLR lenses will require 2 mount adapter
parts:
 MTF Services Adapter (MTF FZ to Nikon Adapter). This Third party adapter
can be acquired directly from MTF Services
 Gates Iris Gear Adapter. This adapter is available from Gates. It provides a
gear interface between the MTF services adapter and the F55 Housing.
Install the Sony FZ Mount
adapter if you are using PL
mount lenses.
Install the MTF FZ to Nikon adapter (blue) to the
F5/F55 camera first. Then install the Gates Iris Gear
Adapter (green) to the MTF mount in the approximate
position shown. A single screw on the bottom of the
Gear Adapter will secure it to the MTF adapter.

F55 Setup Page 17
 Gear Rings When using a DSLR lens, a gear ring is required to slip over the focus
or zoom rings on the lens, which in turn interface with the F55 Housing. Gear Rings
are very specific to a given lens. Contact Gates for details on the appropriate Gear
Rings for a specific DSLR lens.
 Mount lens to the camera. At this time, mount your lens of choice to the F5/F55
camera.
Install Gear Rings onto your
DSLR lens.
Mount lens to the F5/F55
Camera.

F55 Setup Page 18
Lens Gear Drives (LGD’s)
 General Notes. This section
addresses the installation of three LGD’s –
2 x CCW (Counter Clock Wise) and 1 x
CW (Clock Wise). These designators
are applied because two LGD’s point
in a CCW direction and the other in a
CW direction, The LGD’s are marked
CCW and CW.
You will install guide bars and drive
shafts that match the lens of your choice.
A lens cross reference is included in your
F55 documentation package and is updated on
a regular basis. Visit GatesHousings.com or
contact Gates for a current cross reference.
Secure Guide Bars. Insert the guide bars by threading them into the front
bulkhead. Tighten firmly by hand – no tools are required but wrench flats are
provided on the guide bars should this be necessary.
 Install Drive Shafts. These are ¼” black delrin and have a flat spot milled into one
end. This end inserts into the drive coupler at the face of the front bulkhead.
Secure gently with the set screw on the coupler. Do not overtighten.
The F55 includes three LGD’s
– 1x CCW and 2x CW.
Insert the drive shaft into the
coupler. One end of the shaft
will have a small flat spot.
Align this with the set screw,
and tighten gently. Do not
overtighten.
Note: Different Gates housing shown.
Thread the Guide Bar into the
front shell and tighten by
hand.

F55 Setup Page 19
 LGD’s mounting. Install the LGD’s in their proper orientation with pivot gear
screws facing forward. Slide it onto the guide bar and drive shaft, then line up the
LGD with the lens gear you wish it to access.
The sequence of tightening screws on the LGD’s is important.
 Step 1. Tighten the LGD mount screw
securing it to the guide bar. Critical: the
drive shaft/gear hub must be centered with
the opening on the bracket.
 Step 2. Pivot the larger gear onto the lens
gear such that it makes intimate contact.
Carefully observe that the gear is still
properly aligned and the drive shaft/gear hub
is centered with the LGD bracket (see photo).
Tighten the two pivot screws gently to secure
it in position.
 Step 3. Firmly tighten the screw that couples
the drive gear hub to the drive shaft.
TIP. The gear hub / drive shaft coupling acts
like a clutch – the drive shaft will ‘slip’ when
reaching the end of travel in either direction.
Tightening the screw more will allow less slip.
Adjust this amount of slip at your discretion.
Center the drive shaft/gear hub to the
bracket. Tighten the screw and secure
the LGD to the guide bar.
With the drive shaft/hub centered, pivot
the larger gear to make intimate contact
with the lens gear. Gently tighten 2 pivot
screws.
Couple to Drive Shaft .

F55 Setup Page 20
 Set the focus/iris indicators. The left and right side Gear Controls have indicator
rings. These shipped in the parts kit. These are white plastic for marking focus / iris
indications.
Secure the ring with the two set screws in the knob as shown.
 Verify Operation. Once positioned and secured check operation of the Focus and
Iris controls. They should rotate freely – but with slight resistance – in both
directions and through the entire range of travel. If not, repeat steps 1-3.
In a subsequent section “Check Operation” you will power on the camera and verify
the Zoom control is also smooth and operational.
Slip the white ring over the
Gear Control knob.
Secure with set screws
here and opposite on the
knob.
