Fantasea BigEye Lens FXF80 Manuel utilisateur

1. Introduction

The Fantasea BigEye Lens FXF80/100/200 is a patented “wet” accessory wide

angle lens that was specially designed for the FujiFilm WP-FXF80, WP-FXF100

and WP-FXF200 underwater camera housings. The lens fits onto the housing

lens port 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.

2. Technology

The BigEye Lens FXF80/100/200 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 to not cause any damage

to the product.

B. Attach the secure line to the lens and the housing, in order to secure the

lens to the housing.

C. During the dive, install the BigEye Lens by attaching it to the housing lens

port, as shown on the figure on the following page.

Important Notice:

Prior to installing the lens, make sure you are holding the lens according to the shape of

the lens port, so the gap designed on the lens adaptor corresponds with the housing

built-in flash diffuser. To install the lens, push it against the lens port starting from the

bottom right corner (when facing the housing) and proceeding towards the top left

corner, where the housing built-in flash diffuser is located. After lens installation, make

sure it is properly attached by gently trying to pull it out. If properly installed, the lens

should not easily come off the lens port.

D. 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.

E. 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.

F. When taking photos with the BigEye Lens installed, set your camera

focus mode to “Macro”. Failing to do so will result in blurred images.

Built-in Flash Diffuser

G. 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”.

H. In order to remove the BigEye Lens from the housing lens port, first

detach the secure line and then gently push it off, starting from the

secure line loop on the right side of it, using your thumb in an outward

direction as shown on the image below.

I. When removing the BigEye Lens from the housing, it can be secured by

attaching it to the corresponding EyeGrabber lens holder, which mounts

on Fantasea Flex Arms, thereby making it easily available for future use.

J. 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.

K. 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:

a. Make sure that the wings of the BigEye Lens are positioned at an

angle that blocks the strobe output, as well as the sun. In order to

prevent the wings from unintentionally changing position, some

friction has been added, but rotating them can be easily done by

following a simple technique. In order to rotate the wings, simply

hold them and push them against the housing when the BigEye

Lens is mounted on your housing lens port. At the same time,

rotate them around the lens, till they have reached the desired

position. 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.

b. 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.
