1. Introduction
The Fantasea BigEye Lens M67 Mark II is a patented “wet” accessory wide angle lens
that fits onto the housing 67mm lens port thread and can be installed and removed
during the course of the dive. It is perfect for photographing seascapes, divers, ship
wrecks and schools of fish without moving further away from the subject, thereby
still taking full advantage of water clarity and artificial light sources.
The BigEye Lens M67 Mark II can be mounted directly on top of 67mm threaded
housing lens ports or on top of lens ports featuring a different thread, by using a
compatible adaptor.
2. Technology
The BigEye Lens M67 Mark II makes use of a new patented lens technology, which
allows for high quality underwater wide angle images free of distortions. The new
technology uses air instead of glass as an optical element and enables recovering
100% of the camera lens optical properties that would normally be lost underwater.
The air pocket inside the lens enhances the angle of light refraction, thereby
restoring the original angle of coverage of the camera lens (see figures below). This
patented technology was specially designed for underwater photography and
therefore the lens should only be used when the system is submerged in water.

: 5. Instructions for Use
A. Please use the utmost care and do not use excessive force when assembling and
disassembling the lens, in order not to cause any damage to the product.
B. During the dive, install the BigEye Lens by screwing it on to your housing lens
port, as shown on the figures on the following page.
Important Notice:
The BigEye Lens should only be screwed till the point of minimal resistance.
Continuing to screw the lens further than this point will make it difficult to
remove it later on. If this happens, in order to remove the lens, please use a
slight amount of pressure against the dome or plastic protector wings by
pushing in and turning counter clockwise at the same time.

C. Please note that the BigEye Lens was designed to work underwater only.
Therefore, the lens should only be installed underwater, while letting water enter
the gap between the macro lens and the housing’s lens port. Make sure that
there are no air bubbles trapped between the BigEye Lens and the housing lens
port before taking images.
D. During the beginning of your dive, your lens might become foggy as a result of an
increase in the air temperature inside the lens, following submersion in cooler
water. Storing the lens in a cool dry place when not being used, such as a padded
housing bag with a few silica gel packs inside, and submerging it in cool water for
10 minutes prior to the dive, will assist in preventing such condensation.
However, even if your BigEye Lens starts fogging up at the beginning of the dive
due to temperature differences, please note that continuing to dive with it for
about 10 minutes will eventually dissolve the fog.
E. When taking photos with the BigEye Lens installed, set your camera focus mode
to “Macro”. Failing to do so will result in blurred images.
F. The BigEye Lens can be removed and installed repeatedly throughout the course
of the dive. Whenever removing the lens, set your camera focus to the desired
mode, if it is not “Macro”.
G. When removing the BigEye Lens from the housing, it can be conveniently stored
by attaching it to the EyeGrabber F67, which mounts on Fantasea Flex Arms,
thereby making it easily available for future use. For further information, please

H. It is recommended to use an external strobe when the BigEye Lens is mounted on
the housing. The BigEye Lens blocks the camera internal flash, resulting in
underexposed or shaded images.
I. When using an external flash, there are a few techniques that should be followed
in order to avoid a lens flare, which is often encountered when using dome ports
of any kind due to the reflection of the sub or strobe:
I. Images in which the sun is captured can be usually taken during mornings
or afternoons, when the sun is not as strong as during the middle of the
day. In general, the sun will have a much softer and successful effect
during early and late hours of the day and will also cause less of a flare.
II.Make sure that the strobe is not positioned towards the lens. When
shooting a nearby subject, for instance, it is better to position the strobe a
little bit in front of the camera housing rather than behind it (so the light

doesn't reflect on the BigEye Lens), or if you choose to position the strobe
behind the camera housing, make sure it's not pointed directly
towards the lens, but a little bit tilted towards the side.
6. Care & Maintenance
A. Please use the utmost care and do not use excessive force when assembling and
disassembling the different accessories, in order not cause any damage to the
product.
B. Keep the BigEye Lens away from extreme high temperatures, as under direct
sunlight, since it might damage the O-ring and interfere with the watertight seal
of the lens.
C. Do not clean the lens with any chemical solvents or other materials, which might
cause damage to the plastic dome.
D. Never look at the sun through the lens.
E. When storing the lens and during transportation, make sure that it is properly
protected in order to prevent scratches, cracks or any other damage to the lens.
F. After Dive Care:
I. Detach the BigEye Lens from the housing lens port and rinse all lens
components in fresh water.
II.To ensure that the accumulated salt has completely dissolved, it is
recommended to soak the lens in warm fresh water once in a while.
III.Wipe the water drops with a soft cloth. Do not leave any droplets to dry on
lens surface, as permanent water spots may remain.
IV.Store the lens in a dry and protected area. Storing the lens in a low
humidity environment will decrease the chances of the lens fogging up
when submerged in water.
V. Do not store the lens in presence of chemicals, solvents or fuels.
