Gear installation on the lens:
Slip-on gears (gears without mounting screws): Slide the gear over the lens and align on the Focusing or Zoom ring or push until the gear
cannot move any further up the lens.
Gears with adjustment screws: Tighten the set screws lightly and evenly, approximately ½ a turn at a time, carefully working your way around
the gear until all the screws are equally tightened, verify that the zoom and/or focus mechanism rotate smoothly and that the gear remains
concentric with the lens body.
CAUTION: Do not over-tighten the set screws, doing so might bind the lens and restrict the rotation of the Focus or Zoom ring and possibly
damage the lens mechanism. Conversely under-tightening these screws might cause the gear to slip or lose its alignment.
LENS INSTALLATION
Note: Always take extra precaution to protect the sensor from airborne dust or particles whenever installing or removing a lens.
With the camera installed the housing, push the lens release lever ( #20) into the proper position so
has not to obstruct it operation later, through the port opening in the front of the housing install the
lens in the normal recommended way. If the lens is equipped with a zoom or focus gear, confirm that
the gears are properly installed and aligned. Check the meshing of the lens gear with the pinion
gear ( #18) on the housing by rotating the Focus/Zoom control knob (key #16) several times to
make sure the gear rotates smoothly and does not slip.
CHANGING A LENS (REMOVING A LENS)
The Aquatica Housing provides two methods for removing and replacing a lens. It can be done
either from the front by removing the port or through the rear, by removing the camera mounted on
its quick release tray (key # 1)
From the front: unlock and remove the port and/or extension ring (see chapter: Mounting a port
and/or Extension ring on the housing). If a gear is mounted on the lens, access to the camera lens
release button is still possible using the lens release lever (key #19) on the housing.
Or
Pull out the Lens Release Lever (key #19) out of the way, lift and rotate the Zoom Focus Release Disc (key #17) clear, open the housing
back cover, remove the hot shoe from the camera and pull out the complete camera & lens from the housing, replace the lens and reinstall
in the reverse order.
PREPARATION AND INSTALLATION OF THE LENS
There are a number of lens gear available and various way of mounting them to a lens, all depending on their design. Using the right gear
and correctly mounting it on the lens is a very important step for a smooth operation of the Zoom or Focus control. Carefully follow the directions
found on each gear packaging. Please note that the use of Canon EF and EF-S compatible lenses is mandatory. A comprehensive list of the
supported lenses for this housing and their respective gears and domes ports is supplied along with this manual. The lens charts are regularly
updated as newer lens are made available, for the latest available version of this housing lens chart please visit our Lens Chart section at
http://www.aquatica.ca/en/products_zoom.html
Notes: On some lens /dome port combination, a close up lens (Diopter) might be required or desirable. This is intended to correct the minimum
focusing distance of the lens so that it can focus on the virtually projected image created by the dome. Refer to the appropriate lens chart to
see if a diopter is required for your lens/port combination.
Zoom lenses: Mount the gear on the lens zoom ring. The housing focus/zoom control (key #9) then becomes the exclusive method of
controlling the zoom. Focusing of the lens is then achieved by using the camera’s autofocus system, or on certain Wide Angle zoom lens, it
will be possible to access the manual focus via a dedicated port extension ring equipped with a manual focus access knob
Prime Lenses: They can be used in Auto Focus or if a focus gear is available for this particular lens, it can be operated in manual focus. For
Manual operation, the camera focus selector need to be set to the manual focus position, then a focusing gear (if available for this lens) will
need to be mounted on the lens.
WARNING: If the lens is a not of the USM type, never attempt to operate it with the camera in autofocus mode with a mounted focus gear
engaged. This will strain the focus mechanism motor and might damage your lens.
